Really awesome work, something cool (but I have no idea how feasable) would be listening to the song while you jump around. Other than that awesome work
Great suggestion, I had originally wanted to create something like that, but I figure folks can just open up a separate YouTube window for that. Would also love to have the timing be in sync (ala Karaoke) but I'm not aware of any open database that stores that kind of metadata.
I believe MusixMatch has timing data (it's what the Shazam karaoke mode uses), however I'm unsure if the free API allows access to it. Worth a look though. https://developer.musixmatch.com
Thanks jonty, looks like a fine resource, though it's a bit expensive to use ($25000)
