A lot of times I will get a good idea for a mix, but only know 2 - 3 songs that would fit. Not sure if it would be feasible, but it would be cool to have a section for these incomplete mixes that others can add tracks to. Adding tracks could be limited to just the user, just the people the user is following, or everyone.
Hahah, that happens to me all the time. I must have 3 mixes on the "back burner" because I wasn't able to come up with a full 8 songs to round it out, but what I had was too good to throw away, lol.
I love the idea that you could have only people you're following edit, so you know you'll get quality contributions.
Jeff --- www.8tracks.com/duewets !! Go on there, ask an 8tracks friend to make a mix with you or just put one up there and put the title as "open to any" or something like that.
