Listening to music and needing an update

Recently, I’ve become attached to Grooveshark and online streaming website where you can play loads of your favourite songs. However, I still want to update my iPod’s music content. I still haven’t gotten the time though, plus there’s this need for me to check genz-benz amp at guitar center for a friend because he’s asking me if I know anything about it. Pretty much, I guess. I do hope I get to update my music library soon.
