User blog:Thecricketguru/New RWBY Soundtracks?

So in the second episode, we are shown a new soundtrack which plays in the background of the episode as well as a new song, 'I May Fall', which plays during the credits. These tracks weren't released for the public with the initial airing on Roosterteeth.com, so I was wondering if they were waiting to release the tracks when they upload episode 2 to YouTube.

Also, will Jeff Williams be the sole producer of music for RWBY? And will there be more featuring artists other than his daughter Casey? I'm just curious...
