Before I explain, here's what to do:
Select genres from the obvious list of genres, then click My Playlist
Without further ado...
I accidentally pushed the next iteration of L2E to the server that was responsible for hosting the original. It was supposed to go to a different server, but, obviously, it didn't.
I didn't have a backup.
There will be bugs. Links won't work. This will be down sometimes. The design and user experience will change when the beta is released. But until then, you can enjoy the new features (well, at least the only two that matters, which is multiple genres and more tracks) as it stands now.
Check out the Facebook and Twitter for more updates. Feature requests can happen there too, though we think we've gotten most of them down.
