I had U2’s “Running to Stand Still” stuck in my head for a couple of days. Last night I did this to try to get it out, courtesy of an instrumental version from karaoke-version.com and some messing around in GarageBand. Apparently adding a little reverb to your voice can make you sound halfway decent, even using a laptop mic. Now I just need to learn how to mix tracks properly.
Anyway the experiment was a failure. It’s still stuck in my head.
