If you already have audio tracks saved, then you can ignore this step. But if you don't, I'm about to make you realize why this newsletter is (or should be) your new favourite.
Remember Tech-Letter #27? The one where I covered how to download videos from YouTube? That's about to come in real handy.
If you don't have an audio track saved, look for your song on YouTube. You don't have to specifically look for a non-music video, or even the "official" video for that matter. But note, if you choose one of those "live" (recorded) concerts, your end-result tracks might not be as crisp because there's way too much going on in concert videos (people shouting, special effect noises, etc).
After you've found your song, type in pp right before ".com" (step 2).
