Beyoncé: 'Sweet Dreams'

It's not without its faults, but Beyoncé's I Am... Sasha Fierce album certainly has strength in depth. Having already given us a classic-sounding pop song with lyrics about gender role reversal ('If I Were A Boy'), one of the most reliable floor-fillers in recent memory ('Single Ladies') and a power ballad for the noughties ('Halo'), it's now spinning off Beyoncé's first electropop tune.

What's more, it's a bit of a corker. Built on a bassline that wouldn't sound out of place on Thriller or Bad, 'Sweet Dreams' snares you with its irresistible chorus hook, then keeps you intrigued by placing a hint of darkness ("You could be my sweet dream, or my beautiful nightmare...") just beneath the shiny, synthy surface. Oh, and if you're still in any doubt as to Beyoncé's credentials generally, consider this: she's just named her first electropop tune after one of the most famous electropop tunes ever... and pulled it off.
