I'm none too savvy with computers, so I'm fairly ignorant to the whole mp3 thing as well (what was wrong with CD's, or tapes, or records, bah!!!). I think I'm going to have to try and work it out, but there's moments when there's more than just the lead line and bass line, when there's notes in the middle just filling in harmonic space, which I don't think I'll be able to get.
