Yeah, I definitely wouldn't rate Grooveshark 9/10. It's great, and I've happily used it for months, but it's no Spotify. Aside from the legal issues, the sound quality is generally pretty bad, the crowd-sourced music catalogue with incorrect song/artist/album names is maddening, and 9/10 for Mobile seems a high when you have to jailbreak before you can use it on one of the largest phone platforms.
I didn't take points off for having to jailbreak. I reviewed the app for the app, and the app is great. Plus, apparently jailbreaking is easy.
It's true the music player itself is inferior to Spotify, and the quality of search results is not as good. But it's free, I'm fairly certain it has more songs than Spotify, it's accessible from any computer, and it has other features like radio (which from personal experience is slightly better than Spotify's in term of recommendation quality).
