Mp3 editing thingo

Wondering if anyone can help me. Im after some software you can download that can edit mp3s, similar to the way that Windows Movie Maker can edit videos. Ive got local band Illicit Eve CD on my mp3 player, but the last song has this really annoying and unfriendly 13 minutes of silence after the song, before a bonus track starts up. Im after something that can either get rid of everything after the last listed song ends, or pull out the last song without the rest. Any ideas?
