Heck, I felt like having a poll here. What's your tracking speciality? Generating flexible and nifty rhythms, handling samples, making interesting leads or some other skill?
I'd say my speciality is minimalism and composing under strange conditions. In a sense, I can make music with any sample under any condition. This is shown by all my (crazy) alternative music, like Fatal Error in -1, Guns of Counter-Strike and Veggie War (That one is lost somewhere. It was a groove song with recordings of cucumbers being slashed and banged on the bench, haha!).
Usually, I can compose music with anything that makes sounds and that I can handle. For example, I have done several PC Speakers beep loops with GWBASIC and composed on my cell phone's MIDI composer program.
I am also very good at making single-sample chiptunes. In fact, many of my better songs are single-sample chiptunes. I don't know why I got into it, it has just become a gimmic of mine, hehe.
