Yes. Check out Marco Arment's preview.fm. He had a similar web app that allows you to preview album.
Oh yeah, I've heard about it before. I will definitely implement it using <audio> if it doesn't heavily affect loadtime.
Definitely man! That feature will be quite useful.
Thanks.
It shouldn't affect load time at all. Don't load the preview until the user requests it. That's the one feature I thought was missing. Otherwise, it would be awesome. I mainly use iTunes to listen to preview, removing the step to go to iTunes for that would be awesome! :)
