I know I already wrote about pandora. However, if you only got your 40 free hours of music this month from pandora and are hesitant about spending the $37 for unlimited music then switch to Grooveshark.com. Tons of music flows through Grooveshark and you can pretty much personalize it to yourself. It has great functionality and is very user friendly. I am not an avid user yet so I cant exactly fill you in on all of their great functions. I do know one thing though, If you’re Canadian you can actually use Grooveshark, unlike Pandora. Check it out, its easy to use, its sleek, and most importantly it has a lot of great music.
