A useful quote from a veteran UK Indie label boss:
If you get on the right Spotify playlist, it could pay for your album. My friend Ian who runs How Does It Feel to Be Loved has a band call Haiku Salut – they were on a Spotify playlist and it made them a load of money. It’s different from just sending a record to NME. There’s no longer one source that has that single power those magazine had. That’s possibly a good thing, but I feel sorry for a lot of music writers who are expected to provide content for free.
