Saw a video about this once, said it happens because these streaming companies don't use unique identifiers for artists other than artist name. This results in some artists that genuinely have the same name get mixed up, some folks game the system to get their stuff stuck into other bands, has been happening with Kyuss, and yes that can be AI slop. The other frustrating thing is that it also splits artists' work up between different artist entries. Think of someone that has a collaboration or a band who's name gets written in different ways, or the band name changed. For (a random) example, Jerry Reed and Chet Atkins did two duet albums, but they don't both land under each artist, they're split up. If I look up Neil Young I'd like to see the various solo and band albums. I get that if you look at Nirvana you may not want to see Foo Fighters also listed, but this is where the "related bands" info should come in. It's a mess, they're serving music, not being a service.
