They're of CD quality, yeah, but something still sounds a bit unfinished about them to me. Absurd is actually maybe the most 'complete' sounding song - Hard Skool / Perhaps sound like they have the nucleus of a tune that wants expanding/reworking.
Atlas is probably the next 'most finished' tune but even that sounds like it could be extended in some fashion, to Catcher's sort of length with another verse or something.
Bottom line is we're only getting these because of the locker leaks - I truly believe we'd have heard nothing otherwise.
