As a musician myself, I very much appreciate the key change at the end there. You don't hear that much in House. :D
This song is very nice and smooth, but fun. I like the chord progression in it. Good job not becoming too repetitive and changing it up every so often. BTW, you author's comment looks more like instructions than your thoughts on the song. lol.
Please contact me if you would like to use this in a project. We can discuss the details.
