Well... I dont know if this has been suggested before, but I mean, a section where users can upload albums (external links are gonna be required I guess) and others can download them and comment what they think about them, what doesnt like them and what they like about that album.
The section will be separated into genres, and when somebody release something it must be in a specific format, just like:
(An image of the album)
(And a virus scan of course)
And for avoiding law issues about author stuff the albums will come in a rar archive with a text file saying that the downloaders must delete the content between 24 hours or it will be his own responsability.
And please, dont flame, its just that I think its the only thing MPGH is missing in order to become the ultimate comunity
