TTM Case lab — Turn the lyric into two SUNO songs

Trilogy: Foundation / Application / Case lab

TTM Case lab. Paste the lyric. Generate S0, S5, S7. Hear why S0 loses.

Male AUX = S5, piano + sax urban soul, F = 2.93. Female AUX = S7, folk-soul close, F = 2.72. One file only: S5. The woman gives up 0.15 points of closeness. S0 is 2010s trap-pop. Students must generate it too, or they cannot hear the gain.

Numbers are teaching scores, not a listening-lab measurement. Book 3 of 3.

First

• Paste the English lyric unchanged.
• Three styles: S0 (now), S5 (male), S7 (female).
• S5 beats S0 because the function is no longer broken: piano, sax, adult distance.
• Same car, same volume, six-item card.

Four questions

Question	Answer
What does a student paste first?	The English lyric. Unchanged.
What three styles?	S0 (now), S5 (male), S7 (female)
Why is S5 better than S0?	F = 2.93 vs 0. Lyric and age fit. Piano + sax stay.
How do they check?	Same car, same volume, six-item card.

Paste this lyric. Do not rewrite it.

Copy everything below into SUNO Custom Lyrics, including the tags. The piano-and-saxophone line is a stage direction. A scheme that drops both instruments is a reject.

[Intro]

[Chorus 1]
I've seen the really good guys, the really annoying guys, the guys I kinda liked, and the ones I don't care about now
When the pavement's burning under your feet, you find that money's the most important thing

[Chorus 2]
I've seen the really good guys, the really annoying guys, the guys I kinda liked, and the ones I don't care about now
You can let your guard down, baby, just as long as you remember one thing
(Oh)

[Verse 1]
Some folks buy a fancy drink for a friend, but I've watched 'em crawl for a dime on the avenue
Standing on this corner, you see a lot of broken people passing through
After all the crazy things I've said and done, my faith in you was the only thing I'd hold
But the kindness of a stranger on a cold night can be a dangerous thing to be sold

[Pre-Chorus 1]
It's not the lonely fact that you are not around here with me
It's just the thought of you not being in this city makes me feel so lonely, man

[Chorus 1]
I've seen the really good guys, the really annoying guys, the guys I kinda liked, and the ones I don't care about now
When the pavement's burning under your feet, you find that money's the most important thing
(Oh)

[Verse 2]
You could buy 'em all a round of drinks, but a token on the subway line is a more beautiful thing
It's all about believing in the things that this city will never bring
You might be on the other side of this crowded island now, but if you're alive, maybe our paths will meet someday
But so you don't get hurt, you learn to fake it and push the hurt away

[Pre-Chorus 2]
It's not the aching feeling 'cause you are not around here with me
It's the thought of you not being here in madness, that's what aches, you see
(Oh)

[Chorus 1]
I've seen the really good guys, the really annoying guys, the guys I kinda liked, and the ones I don't care about now
You can let your guard down, baby, just as long as you remember one thing
(Oh)

[Instrumental Break]
(Piano and saxophone take a soulful, slightly cynical solo over the city's hum)

[Chorus 1]
I've seen the really good guys, the really annoying guys, the guys I kinda liked, and the ones I don't care about now
When the pavement's burning under your feet, you find that money's the most important thing

[Chorus 2]
I've seen the really good guys, the really annoying guys, the guys I kinda liked, and the ones I don't care about now
You can let your guard down, baby, just as long as you remember one thing
(Oh yeah)

Fifteen minutes

1. SUNO, Custom, Custom Lyrics on.
2. Paste the lyric once. No artist names.
3. Style = S0. Keep one clip. Label S0.
4. Same lyric, style = S5. Label S5.
5. Same lyric, style = S7. Label S7.
6. Parked car, same volume. Mark the six items.
7. F = V minus S0. If S0 wins lyric-fit, the lyric was rewritten or the weights moved after the fact.

A student who only generates S5 hears a nice song. They do not hear a gain.

S0 — generate the zero point too

2010s trap-pop. 140 BPM, 808, glass synth, early-twenties voice. No piano. No saxophone. Radio still plays this shape. That is why it is today's choice, not because it fits.

A 2010s American and Canadian trap-pop and streaming-era pop vocal track around 140 BPM: hard 808 kick, glassy bright synths, busy hi-hats, thin digital bass. An early-twenties male lead, bright nasal tenor, belted chorus, radio-loud high end. Phone-speaker mix. No piano. No saxophone.

S5 male, S7 female

S5 (male AUX)

A mid-2020s Canadian adult alt-R&B and live-band soul song for a night Highway 401 drive, built on a dry mid-tempo groove around 100 BPM: warm Rhodes electric piano, tenor saxophone answering phrases, clean hollow-body electric guitar, analog drum kit with soft snare, rounded electric bass, muted trumpet accents. A thirty-something male lead, warm smoky baritone, intimate close-mic delivery, controlled verses opening to a restrained chorus, no belting. Literary English lyrics about city money, strangers and the person missing from this town, tape-warm production, cabin-ready midrange, late-winter Ontario highway atmosphere.

S7 (female AUX)

A mid-2020s Canadian indie folk-soul song for a Highway 401 night drive, sitting on a patient 94 BPM pulse: felt piano ostinato, nylon and steel acoustic guitar, warm tenor saxophone fills, rounded electric bass, brushed drum kit, subtle analog pad. A thirty-something female lead, husky velvety mezzo, breathy intimate verses opening into a poised non-belted hook, clear diction. Literary English lyrics of pavement heat, money and a lover not in this city, dry-warm analog mix that cuts through road noise without glare, winter-glass windshield atmosphere.

One file: ship S5. Write the price. To keep S5's band and change only the voice, replace the male-lead clause with: thirty-something female lead, husky velvety mezzo, intimate close-mic, no belting.

Why S5 and S7 beat S0

The lyric asked for piano, saxophone, and an adult distance from money and strangers. Trap-pop at 140 BPM with a young belting voice fights every one of those constraints. The gain is not "more trendy". The gain is "the function is no longer broken".

Item	W	S0	S5	S7
Highway midrange	0.18	3.0	4.8	4.1
Low fatigue	0.14	2.0	4.7	4.8
Age 30s	0.14	2.2	4.8	4.8
Lyric fit	0.20	2.0	5.0	4.4
Year fit 2027	0.16	1.2	4.8	4.8
AUX male / female	0.18	3.2 / 2.4	4.4 / 3.4	3.0 / 4.9

S3 is 2024-25's number-one shape (bar song). It still loses. Year-fit is the last weight. S6 (club / hyperpop) is a reject. Do not put it in the average.

Replay 2023 and 2025 with the same schemes and weights. Change only year-fit. The same two styles stay on top. That is validity. It is not a hit prediction.

S5 lives at 94-104 BPM. Mute trumpet can replace sax. 128 BPM, no sax, or an early-twenties voice drops the score. Do not call that a tolerance design. There is no money.
