I had an Alexa ~4 years ago, and I found that (a) it seemed to keep switching to playing clips from songs on amazon music (which I don't subscribe to) vs spotify (which I do) and (b) it would often play a very odd version of common songs when promoted. Like I'd get a live version some other nonstandard version, when searching for the song in spotify gave the album version. I wonder if whatever difference exists in their search process vs the standard spotify way could be responsible for what you're seeing as well (edit, though I realize you didn't have this problem before). Anyway, I stopped using alexa because music was all I found it useful for and it became a pain, and not worth the privacy implications
