So I have a song that I want to edit. I have to use it in a presentation but it's too long, I have to cut it down to three minutes. What sort of program could I use to nicely cut parts out? It doesn't have to be easy (although I'd prefer that) but it should end up with a reasonably nice transition. The song is just the instrumental part of a rap and it's got a nice beat, so if someone knows how I can just clip a section out the transition should be okay.
