Audio bulk upload and metadata editing

I am using drupal to create a site that will allow the user to upload mp3 files and create a playlist from these files. How I have it setup is the user creates a content type "playlist" and then from there using Drupal's default file upload/attachment feature the user can add mp3s to the playlist.

The problem I am having is I want the users to be able to edit each mp3's id3 tags to add artist and song titles to each track.

I tried using the audio module to accomplish this, but the problem I had is I want the user to be able to upload multiple files at a time and I didn't see where this module facilitated that functionality. The audio module's import feature was the closest it offered to what I wanted. The only problem being I didn't think that for a regular user it was the most intuitive way to create a playlist.
