I haven't actually decided yet; there's a couple of things I'd like to do but I'm not sure what you're looking for exactly--does both source and song need to be "foreign", or does either (foreign source with English song/ UK or US source with a foreign song) work as well?

No idea about the length (yet) but I'm prone to cut songs so that they're no longer than 4 1/2 minutes, generally, and usually pick songs that are at least 2 1/2 minutes long, if that helps?

(I most certainly did :) )
