I’ve noticed this quite often. For example I had Nirvana’s In Utero in a ‘rock’ playlist. Apple Music decided to replace it with a Super Deluxe version of the album that has live tracks on it as well. I’ve noticed with other albums instead of serving up the studio album version of the song it gives me a live version (sometimes while still showing the studio album artwork). Or it replaces the studio album with a greatest hits album. This isn’t me asking Siri to play something it’s me adding a specific album to a playlist and then AM deciding to replace it with something else. Quit’s annoying.
