Blog with searchable mp3s and manual registrant approval system?

Hi all,

I’m quite new to WordPress so if someone could point me in the right direction I’d be grateful!

I am setting up a blog for someone who has a catalogue of music.
He would like users to be able to login and search the mp3 catalogue via genre & category and then download the track.
He also wants to be able to manually approve each registrant.

I’m guessing that I need to find widgets for the various elements, search by category, login functionality and download mp3’s..

Does anyone feel this will be feasible without much php coding as I want to avoid that if possible.

Many thanks!
