Is my MP3 ruined if it got into a hot tub???

ok...i was at my friend's b-day party and we were all going to get into the hottub. I forgot that my MP3 player was in my pocket and I got in. I didn't realize until after we had gotten out that the player was still in my pocket. So, the only hope i have is that...well...I think that maybe it only fried the battery cuz the battery seems to only have enough power to turn the blue light on...so im hoping that it will be okay once it dries and i get a new battery. If not, i hope i can get it repaired instead of buying a new one cuz i just got it 4 days ago and it was about $90.00...........HELP ME!!!!!!!!!!
