Obscure algorithms often make us wonder about bias I guess - are they skipping those songs for a reason? Financial? Their own moral code... You can make a conspiracy out of everything.

Exactly. I went through multiple mental cycles trying to determine if there was some kinda underlying motive to the rigged shuffling. In the end, it doesn't really matter whether there is or isn't something nefarious. The critical point is that obfuscated processes can foster conspiracy theories.

Those kinds of moral decisions have to be removed because they just pollute the whole thing with no meaningful purpose for the user.

I've been through a similar scenario. I worked for years on applicant tracking systems. We had this fancy comparison engine that would try to do a "smart match" between a job description and the applicants' resumes. Then it would assign a score and sort the applicants from best-matched (theoretically) to least-matched.

For some of our big corporate clients, we had to disable this feature. The reason was that, to comply with federal hiring statutes and liability concerns, the companies had to keep records of tangible qualifications that had led them to choose one candidate over another (as a counterpoint to the idea that they may have hired the applicant because they were male, or white, or whatever).

But if they were sorting candidates by our magic (meaning: obtuse) algorithm, there was no way that they could satisfy the audit requirement. In fact, their lawyers informed them that merely having this feature enabled in our app represented a liability to their company. Because if it was enabled, and some hiring manager sorted by that "magic" number (whether it was by accident or on purpose), that could theoretically bias the hiring manager in favor of a criterion that they could not define.

I guess the moral of that is: if the user thinks it's broken, it's broken. If two or more users would have conflicting views you have to give them the ability to solve the problem in a way that works for them.

Absolutely. That's definitely my biggest frustration with the Spotify anecdote. I couldn't care less that they wanted to create their own fancy "better" shuffling algorithm. But when they did that, they removed the basic algorithm - the one that did real shuffling.

There's an overall air of condescension there that I've actually seen in many other companies/apps. It's this mindset that says, "We've decided that this is the best approach for you. You're welcome."

To me, it's particularly galling on the shuffle algorithm. They changed it because so many people didn't understand/appreciate what was happening when it was just a simple shuffle. I get that. But I do understand/appreciate it. And I definitely want to have the option for a real shuffle.
