To vote give me five one-hit wonders by 30th October - if you order them 1 to 5 you'll earn more points for your favourite tunes, if you just give me five they'll score equally - vote via the usual mechanisms (blog comment, Facebook, Twitter or Pub) and I'll compile the list for an early November reveal.
