I work a late shift so most of my practicing is done late at night. I have a small crappy practice amp that I use with headphones but I would like to practice with a metronome going through the headphones as well. How would I do this?
Stuff I use:

Schecter C-1 Classic
Ibanez RG350DX
Peavey 5150 (Signature)
Marshall 1960AV

You can download Audacity and plug your guitar into the computer and the computer into headphones, then generate a click track and play over it?
