I don't understand their pricing options on that EP of theirs (they call it a "four track single).
You can download each track for 99p, but the whole thing costs £4.00, and one of those tracks is a "radio edit." I mean, why would you want a radio edit?
Sounds nice anyway... As for prog, I'm not sure, and I don't think it matters anyway.
I might keep my eye on these...
