I've got some songs with which I want to rehearse. They actually become my accompaniment and I play the main melody. However, I really get tired of rewinding the song, playing it again and trying to get into rhythm. I want to cut part of the song such that when I loop it in a player, it sound a continuous song, so that I can rehearse the same piece for longer intervals.
What do you suggest? What software is good for this purpose?
