Cannot upload mp3 flash

i’m not sure if this is related to flash or not… my audio file which is part of my flash mp3 player cannot be uploaded into becuz it does not allow mp3 types… is there another way to upload into brinkster or is there another free webpages which allows mp3 uploading?

ps i chose brinkster becuz it does not have banners or pop ups … could u recommend some which have no pop ups too thx :eye:
