Adventures w/ garageband

I finally have time to tinker in the studio again, and since I'm sick of my own songs, I've been jollifying myself with covers. Moving the iMac to the basement has brought it close to the musical equipment; as such, experiments with Garageband have begun. I'm not a big loops dude, and I'm veering away from MIDI sequencing these past couple years, so I use Garageband as a straight audio and overdubs recorder.
A simple example is my cover of Randy Newman's homage to law enforcement officials, Jolly Coppers on Parade [3616 Kb m4a audio], from Little Criminals (Lyrics at randynewman.com).
An easy way to build up a cover is to drag the original track from your iTunes playlist into Garageband, which creates a track for it. Then you overdub parts on new tracks by playing or singing along with the original. It's great practice and it helped me appreciate Newman's arranging skills that much more.
