The access to Spotify is also super easy. I was in bands and unless you were already popular or had a record deal, getting your CD in stores was almost impossible. I managed to get my bands CD into all the hot topic stores in my state but it was a huge undertaking for a 20 year old kid that just wanted to play music and knew nothing about getting upc codes and negotiating margin and managing inventory.
When Spotify came around I was able to put my music up with about an hours worth of work which was mostly entering banking details, uploading the songs and artwork, and writing a blurb.
I honestly want to start a record label just to put all the local bands I used to play with up on Spotify. Most of them broke up just before the barriers to entry fell down and now the music is lost forever.
