Is it possible to upload files for collaborative projects and such?

Hi,

I'm hoping someone can give me some suggestions with a really simple problem I'm having. Just so you know, I'm moderately experienced with Drupal so I'll understand technical talk.

Here's what I need to do---allow users to upload files to my website. (simple!) The purpose is to make a place for users to upload files for collaborative music projects. One person uploads a song, another person revises/adds to it, repeat until the song is finished.

My approach would be to have one page/blog/story for one project, allowing users to attach revisions and discuss the project through comments to that node.

Here's what I've tried so far:
First I tried the Upload module, but it would only let me attach files to a new page, not comments or forum replies. This means an entirely new page would have to be created for every revision. Not good for workflow.
Next I tried using FCKeditor, hoping to allow collaborators to upload and attach songs through the textarea editor. The FCKeditor built-in file browser is buggy and would only allow me to upload images.
Then I tried using IMCE module plugged into FCKeditor. This didn't work either. The only way to upload a file through that was to click 'insert image', then choose 'browse server' from the menu. After uploading and choosing a file, nothing would appear on the post.
Finally, I got rid of FCKeditor and installed the WYSIWYG API module, and installed TinyMCE to it. TinyMCE still only gave the option to upload images, and gave "invalid file" errors when I tried to upload anything other than images.

Can anyone offer a solution or suggest other things for me to try?

Many thanks in advance
