I use SSD, and it contains drum loops I can just drag and drop into logic.
Recently I have started doing something extremely cool: I use Logic's "drummer" which is a (really nice) virtual drummer software, but instead of the included drum sounds I use SSD (

It's also good because drum programming has always been difficult for me (usually the thing that stops my creative flow), and now its a breeze. Let's just hope not too many others will discover this trick, or we'll all end up sounding the same. Oops I think I have said too much now
Also, SSD lets you STACK DRUM SOUNDS!!!!! A KILLER feature that sadly EZ drummer does not allow. So you can stack four killer snare drums for a SUPER SNARE!!
Cool, I hadn't thought of that!
