Adding new music to MySpace

I have been trying to find out exactly how long a musical piece can be to be uploaded on the MySpace web site. I can't find that it tells that anywhere in the FAQs, Terms, etc. Today I deleted one of the clips we already had on our MySpace page, since we had the limit of four, and decided to just try to upload a new session. It looked like it was almost going to make it.........but, unfortunately, the file was too large. So, we'll just have to wait to get the newer sessions on the MySpace page until clips can be made of them. In the meantime, the new sessions can be heard in their entirety on music2work2.com.
