I'm perfectly ok with Spotify. You have to register and establish an ID and password but it's free and there is no obligation to subscribe to anything or receive emails, etc.  I never use it to scout out new things to listen to.  I use it to find and listen to an album I can't find on youtube.  Both of them suck because of advertisements but they are better than listening to radio for my purpose because I can choose the albums and tunes to play.  For discovery of music new to me I will sometimes click on recordings that come up alongside whatever I'm playing on youtube but mostly I just read this forum.  Generally I use these services to listen to an album before buying - my music budget is limited.  

👍 Now:

So reading this, it seems mostly a nuisance and I don’t get why people are getting really mad about it (rather than just mildly annoyed) Lets say something comes on that pretends to be Nat Adderley but is obviously not him… you can just skip the track! Fwiw, I strongly agree Spotify should stop this kind of thing
