I don’t work out near often as I should (shush Daniel) but when I do like most people I like listening to music. I’ve uploaded music to my iPhone but my library was limited and there wasn’t really any CDs in particular I was interested in buying, and then I’d have to upload it to sync it to my phone (which can take forever). Then I used the Pandora mobile app for a while, and in traditional Pandora style the “stations” began playing songs all over the place. Then the ads, my word the ads just drove me nuts. Then a few months ago I heard that Grooveshark has created an HTML 5 version of their site for mobile use. So I checked it out, and I liked it. But it was missing a few things.
