Cool idea. On Chrome the scrolling likes to shoot me to the top occasionally some period of time after a page switch (probably when it is finished loading all the 'M' songs for example).

EDIT: Your discover page loads every single record on that main page (/discover), generating one HUGE page, (which I can scroll down while it is still being generated), and then once finishes, forces user view back up to the top, as it generates the "0-9,A-Z" menu. There is ~5 seconds delay for me before it finishes loading everything, there should be a better way to do that :)

Also, how about some feedback when a search returns no results? I wasn't able to tell if it was working or just didn't contain any Muse.

Finally, should mention this (appears for now) to be Piano only, and looks to be linking mostly Youtube videos that have been somehow determined to be instructional. (Is there a way for you to detect if a video has embedding disabled? I found a few 'dead' vids because of that.)

Again, neat idea :)
