Where is my League Soundtrack Volume 2?

With all these great songs I keep hearing at the log in screen, I'm curious when/if a Volume 2 is in the works.

From the southern twang of Tom Kench's music, to the outstanding URF 2.0 dubstep, to Arcade Riven's pixel heaven, I can't help but to sometimes just sit in the log in screen and wait to log in for a bit while I listen. The compositions Riot puts out in these things is music to my ears [/pun] Sometimes Jinx's song comes on my playlist, and I remember loving the video but thinking the music was subpar (good, but just has a slightly bland sound compared to the newer songs). Then, just patches later, comes Braum's majestic log in, side by side with that outstanding mustache.

Riot, is there any word on the second volume coming out? I loved hearing the songs from the first one, and await volume 2 with bated ears.
