whats the best program that I can download that I can make a drum backtrack? It has to be compatible with Ableton Live 5.2

I couldn't think of any other place to put this so I put it in the Pit.
My obligatory gear list

Schecter C-1 Classic
Gibson SG Special
1987 Fender Strat
Epiphone PR-150

Amp and Effects
Peavey Valveking 112
Boss DD-6
Crybaby Wah-wah
Ibanez TS-9DX
Banshee 2 Talkbox

If you could blow up the world with a flick of a switch,
Would you do it?

If you could make everybody poor just so you could be rich,
Would you do it?

With all your power,
What would you do?
I use Acoustica Beatcraft
It's not bad and it's not a huge file to download
ohai little sig.
