So I got a link from sabrefist to this program called hammerhead. Its awesome. You can find it HERE

Basically you open it up click on the tab things where you want the drum beat to go, Change the drum beat via the drop down menu, Change the tempo, distortion all that. then press play, Hear it change it then export it to wav.

I attached a drum beat I created.
ZIP FORMAT. Unpack and you'll get 2 .wav files. Play them..
