I use Pandora, Spotify and Grooveshark. For some reason it's hard for me to listen to the same song over and over, so I usually don't buy the song and keep it on my phone. I use Pandora mostly, because I like finding new bands and songs. It keeps me interested. There are a few songs that I really like, and have it on favorites on grooveshark so I can listen to them on replay, but most of the time I use Pandora and Spotify.
