There's a limit on the maximum file size for files you're hosting on your Graal server. The idea is that they don't want you uploading copyrighted music. If you can show them that you're creating it yourself somehow, they'll raise the limit (and have in the past, even for UC servers iirc).

Alternatively, throw them on a server somewhere (or maybe on S3) and just play them from a URL. This is a supported way of playing music, but afaik it means MP3 files won't cache clientside.

edit: max file size was 1 MB as of Jan 2007 per Stefan, but I think it's been raised since then.
