Someone has probably suggested this but I didn't see it in a search. Yesterday I was browsing through artists with thumbnails and I found my self pressing the down arrow in time to the beat. The row of thumbs at the top would scroll off the page and a new row would appear at the bottom, all in time to the music.
How cool would it be if this were automated? Doing it to the beat might be too much to ask, but what about setting the page to scroll at user-specified intervals? It would look a lot like those panes in a jukebox as you browse.
