Spotify and Grooveshark

I recently set up accounts on Spotify and Grooveshark. Here are the playlists:

So far, Grooveshark seems to have a better collection of music that I like. For example, I was able to find some TV, movie, and video game soundtracks on grooveshark that were unavailable on Spotify.
