Time Sequences the new youtube added a good feature, for once.
I'm not sure what's the official name of the feature but this
thing allows you to sequences timestamps into the player.
Like for example, 03:47 / Title Theme will show up on the player
as 03:47 - Title Theme and we are able to click into that timestamp in the player as well.
