Hello. Is there an application for the following? Ahead of a dance party, I'd like to create a dance sequence using songs already in my iTunes library. First step would be to choose a song, and then within this song choose the exact second in the song which I'd like to start listening to it, and then the exact second in which to end that particular song -- in that way eliminating the portions of the song which are not danceable. After doing this for say 20 songs, I'd then like to be able to put the now shortened/edited songs together to create one long dance segment, and save this as a Playlist. All this without losing my original songs in their entirety, of course. Super duper simple application is important because I am not technologically proficient. Thank you.
