I use Cubase SX3 and the occasional Reason on Windows. I focus more on melodies and progressions than the actual "radio-readiness" of my productions. Nevertheless, someone might like the stuff.

Here is my most recent short instrumental piece: http://www.tshaddox.com/wp-content/uploads/2009/08/the-point... . Here are two full-blown songs with lyrics, they are both light-hearted and sort of geeky: http://www.tshaddox.com/wp-content/uploads/2009/03/falling-f... and http://www.tshaddox.com/wp-content/uploads/2009/03/science.m... . All of my compositions are be found here (along with the ability to stream the MP3's): http://www.tshaddox.com/?cat=10
