We removed the ability to upload MP3s because it was not sustainable in the long run. Even with only 10 or so active users right at the very beginning we were still racking up at least 7-8Gb bandwidth each month. Our present hosting (I believe) allows for up to 200Gb of monthly bandwidth but we didn't want to have to suddenly remove everyone's MP3s when the day came to restrict uploads.
So the short answer is as follows: Thanks very much for offering, but we'll decline for now.
