Copy and modify a song (start/stop) WITHOUT loosing original
I teach fitness classes so I need to modify start/stop times in some of my tracks/playlists BUT when I do this the same song which I have in other playlists changes too. I know how to splice a song using start/stop but how do I do this without loosing original song (downloaded from CD or website)?
