Plugin – Database for adding file downloads

My apologies if this exists already.

I want to make mp3s available to download. Right now I’m entering each song manually onto the page.

I’d like to be able to populate the MySQL database with a catagory, song title, download link, file size, song length, a note (optional) and a ‘real more’ text field. I’d then like to be able to pull this info into a page in WordPress. Is this in development or does something like this exist already?
