It's rather ... Heidi-heavy.

Which clearly means that it is AMAZING!
The Sugababes premiered the second single from their upcoming album this week, nearly a month before the first single from the album is even released. If you read a few posts back you can hear the first single 'About You Now', but this one, 'Denial', is even better! It's rather drum'n'bass and slightly electro-pop in bits. But the best thing is that Heidi sings the ENTIRE song.
