So Katy Perry is following up her multi-bazillion-selling six-number-one-hit-spawning album Teenage Dream with her latest effort Prism and we've gotta say, we're already pretty hooked.

No doubt 'Wild Horse' featuring Juicy J is our top "unexpected hit" bet but funk-infused 'Birthday', dance mad 'Walking On Air', earnestly atmospheric 'Unconditionally' and very 90s-sounding 'Spiritual' could all do well in the charts too. The thing is, things aren't all super-neon kawaii happy happy cake-boobs funtime so there's a definite sense that Ms Perry is changing direction.

Have a listen below and let us know what you make of it. Go on. Broaden your horizons. Try a bit of pop. You might even like it. The full album release is October 22nd.
