Solution for mp3 Upload problem

Hey Everyone.

I recently had a wordpress site built a while ago, and i am trying to Upload mp3s to the media library. These mp3s range anywhere from 13MB to 60MB.Is there anyone out there who has successfully uploaded mp3s this large? if so, can you please help me with this! I know that there must be a solution, because there are many wordpress sites with large mp3 files on them. if anyone can help, I would greatly appreciate it!
