MP3 song cutter app (not for ringtone)

[ireknole]

I'm looking for an app that well let me cut a portion of a song, and keep the rest of the song in its entirely. Most of the MP3 cutter apps are made for ringtones, so they automatically cut the remainder to 50 seconds or so. If I have a 3 minute song and I want to cut out a minute off the beginning, I want the remaining 2 minutes saved, not 50 seconds of those 2 minutes. Does anyone know of an app that will do this? Thanks!
