And Tool. I think it's a conscious decision on part of those bands / rightsholders since they know that fans will go buy their music anyway, so they don't have to settle for the cheap stream fees.
This is why I like Google Play Music, you can upload 20,000 of your own songs to fill in the gaps (which are increasingly few and far between)
I have Google Play and Spotify. I typically play local files through Spotify and that fills in the blanks as well.
And Thom Yorke. Which doesn't stop them from telling me "You haven't listened to much Thom Yorke recently, want to now?".
I should've said "EVERYTHING.... that I like to listen to". There are definitely gaps.
