I have musical ADD. I can't listen to the same song twice and alot of times I can't even get through a single song. It bugs the hell out of me when I visit my friends' profiles and hear the same song over and over again. One way to solve that problem is to add a radio station to your profile. I just added a stream of one of my favorite online radio stations, KEXP to my profile. KEXP almost never plays the same song twice which takes care of my musical ADD problem. You can get scripts to stream radio on your profile for almost any style of music over at myspacescripts.com.
