I'm not sure about the plausability/legality of this idea, but here goes.
The Music Banter Ark
Members could upload all of their music collections to a set of servers. All members would have access to everyone's music. With all relavent content at hand, music discussions would be much more efficient. The communal sharing of files would help everyone assimilate with one another. Every members' musical collection could be displayed on their profile page. If a member wanted to listen to a new artist, they would have a generous index of musicians to choose from, as well as reviews and commentary on each artist. Members could download and uploaod content at will. The possibilities are endless. I realize that this would require copious amonts of time and effort, but the end result would be stupendous. Every members' taste of music would be accounted for. MusicBanter could be a vault of music from each constituent of the site.
