I stopped buying music this January as a new year's resolution, and haven't spent a cent in 2014 despite listening to songs over 3,300 times this year.
In order to do this, I signed up for Spotify and installed the desktop client on my computer. Although I can't listen to music on demand on mobile that doesn't matter to me very much because I use iHeartRadio on mobile.
Yes, completely. And it's great. It's really expanded and broadened my music taste, where as iTunes limited what I would listen to and actually put money into purchasing.
