Hi, World of Android!

I have a T-Mobile G2. My bare-bones gym has wall-mounted TVs. In order to hear the TVs, you have to tune in to various radio frequencies (not regular radio stations, of course). I need an easy-to-download FM radio app, not one with pre-set radio stations. (easy, as in no scary dev stuff, zipped files, etc. Just an app.). I downloaded TuneIn, which is a cool app, but it doesn't serve the purpose for the gym TVs. I can use my headphones as "antennas."

Can anyone help? I want to hear the TVs when I work out!
