Anyone's TP2 really warm after listening to music?
 

Today I noticed that after a couple (2-3) of hours listening to mp3s using WMP with my TP2 in my front pocket that the phone was really really warm. Has anyone else noticed this? I haven't really used my phone to listen to music for more than say 30 minutes until today. It's not like my phone was plugged in and charging right before either.

I used it surf the web and watch a few videos for maybe 2 hours a couple of weeks ago when I was traveling, and I didn't notice this heat issue.

Has anyone else experienced this?

EDIT: I think my problem was using WMP, I switched to Nitrogen 1.2 uses less memory and didn't cause my phone to heat up.
