Today I've been educating myself by finally listening to The Strokes album, and I can confirm there are another 9 tracks alongside 'Under The Cover oF darkness' which you'll hear every 30 seconds on 6Music (which I know HAVE to have on in the background apparently).
However, I suggest you go and have a listen and watch 'Air Waves'. I just downloaded their current album and it's excellent. They are touring the UK later this year, so go and buy tickets when you can.
