This is how I feel.

You can right click it and choose audio remix from the context menu if it's not an animated gif.

@Anonymous: There are two sliders on the same bar (actually 3 because you can drag the playtime slider as well while previewing), the first one is the start time.

@dmauro: There should be a number to show what time the play slider is on.
Decimals in the times work when you drag the sliders but not when you type the numbers in manually.

@Anonymous: YOU ARE A PIRATE

@Anonymous: Click remix and copy the youtube url.

@Anonymous: Yeah it could use some tweaking. Part of it though is that it's hard to get the exact start time you want because of how Flash does streaming audio, but I'm definitely going to try to smooth that out.

@eku: I don't think they have an API for that, is the problem. I see http://code.google.com/apis/youtube/iframe_api_reference.html, but it says "You should not yet build business-critical applications using this API nor should you launch any applications using this API into a production environment."

So, it sounds like it might be possible at some point!
