I am using your Music Collection plugin along with the invoice manager. As a producer, I may want to sell my beats to other artists, so I saw Music Collection and was like... PERFECT. However, I can't use it for that purpose. I think it would be a wonderful idea to integrate Music Collection with Invoice Manager DEEPER.

For example, I can add a pay link but isn't this what Invoice Manager should do? I can create invoices but not inside Music Collection.

Can you help me with this?

Also, with Music Collection, it would also be great to have a "PREVIEW" of only 30 Seconds of a track like iTunes, etc. They do this because its the LEGAL way to hear music before purchase.
