mp3 collection module

Hello everyone.

I've been using jinzora(http://jinzora.com) at home for my mp3 managing and consumption needs and some of it's quirks almost have me wanting to get rid of it.

it seems that drupal would make an excellent foundation on which to build something similair on and a quick search of the modules around here confirm that some wor has been done from specializing flexinode to a creating a module for this purpose. However, it doesn't have all the features that I like in jinzora. So, I'm wondering whether there is development going on in this area that I could use/contribute to, or just go it alone and write my own.

Here's the features I want/need(not necessarily complete).

1: configure a list of directories on the server containing mp3s
2: Periodically read id3 information from mp3s contained in the directory list and populate the database or remove database entries that no longer exist on the disk(jinzora does not do this).
3: List of artists, albums,songs
4: artist view showing all albums and a bit of information about the artist (play all albums, order by year released if available)
5: album view listing songs in order by sequence play album, play individual songs must work properly on albums with various artists as well(something jinzora does not do)
6: song view showing all id3 tag information available option to play
7: playlist creation, playlists saved/shared etc...

Anyone know of any efforts in this area? Or am I doomed?

Any help/guidance/info on this would be much appreciated.
