Good touchscreen music app? (S2P not quite there)

[SweetBearCub]

Greetings.

I'm looking for a good music player app for listening to music at the gym.

I've tried WMP with SPB MS 3.5 home screen controls, but they are too small to easily grasp while working out. Next I tried S2P. Better, but still not as easy as I'd prefer.

Is there a music player that can put a HUGE control pad on the screen with FF/next, REW/back, play/pause, and that can skip to the next song when I shake the phone?

S2P supposedly supports advancing to the next song by shaking the phone, but I tried it at home and it didn't work. The sensitivity was on a scale of 0-200, defaulting to 100. The lower, the easier. I lowered it all the way to 0, still no dice, and I shook the phone pretty hard. It would be a handy feature to have at the gym.

Also I noticed that my phone heated up quite a bit during my S2P tests. Does it have a known battery drain issue?

Is there anything better out there?

Thanks.
