I did make the switch to Spotify (although I don't really watch much youtube, so youtube red wasn't a blocker for me). I haven't been super thrilled with Spotify's ability not to repeat the same songs okay the course of a few days when I listen to it throughout the day while working, but I'm slowly having success getting it to give me more variety. This might just be due to me having a smaller set of music that I'm interested in listening to (classic rock, progressive rock, and some blues) compared to their average user who might be willing to listen to anything popular from the past several decades of music, including new stuff as it comes out.
