just tried, and I appear to be getting stuck on "fetching song list .." screen too (tried a couple of random searches). I wonder if it's related to the changes to the main website interface?

Either way, I'd love it if dotblank would give us a short update on his plans (if any) for the app in general. I find Groove to be one of my most useful n900 apps, even in its current basic state. If the on-screen buttons have functionality added one day, it would be really excellent :-)
