I used to be totally obsessed with GetTunes... except it stopped working after the itunes 4.5 or 4.6 updates. OurTunes is okay, it works pretty well. I liked the look of GetTunes better, but beggars can't be choosers

The good thing about OurTunes is that it lists everyone's music on the network in the OurTunes window, so you don't have to play the song on iTunes to download it (like you do with GetTunes), you just highlight the song(s) you want in the OurTunes window and hit download, and the songs will be put into any specified folder you want.
