I need some music for a project, and I'm using "Nobody's Home" by Avril Lavigne, but the lyrics don't actually start until like 20 seconds into the song. So I want to cut off some of the music, but I need a good program to do that. It can't be something where I have to pay, and I don't want it to have viruses. A computer program would be okay, but I would prefer one I can get on my iPod Touch. Keep in mind that it only has iOS 6, as it is a 4th generation iPod.
