data streaming question for the smart phone techies

I was wondering if anyone knew how much data is used when you stream audio of a hockey game on your smart phone (and using the smart phone's data plan). I drive across alligator alley on Friday nights, thus miss quite a few of the Cornell games. I was thinking that if I actually have signal while on that stretch of I-75, I could in theory stream whcu's audio feed of the game.

I'm on a limited data plan (AT&T, if it matters), thus curious about how data that would suck up.

TIA.

Looks like the whcu stream on TuneIn uses 32 kbps = 4 kBps. Three hours of streaming that will come to roughly 42 MB of data usage.
