Wow. Now that I understand what it is for, the download any button is (or would have been, it's gone now) incredibly useful.

Say I'm looking for a rare song, and I get results in 6 different bitrates. I could start them all, and cancel the rest when one finishes, or I could use the download any button. It would then try them all until one finishes. It's brilliant. Really. I hope you put the option back in. Or maybe I will myself. Wish I'd known what it did earlier.
