What's hot on our playlist

Jason Isbell and the 400, Unit Sunstroke

Brooding, organ-infused Southern country-soul number treating those twin imposters, ambition and failure, with equal suspicion.

Aidan Moffat + the Best-ofs, Oh Men!

Ex-Arab Strapper sums up the war of the sexes in three wise, raucous minutes – and surrenders.

Florence and the Machine, Rabbit Heart (Raise It Up)

Joyous, swirling harp and keys from the songstress. Sure to be a party hit.

Rumble Strips, Not the Only Person

Underrated Devon band return with a confident, stomping piano and strings pop number and the Mark Ronson treatment

Mos Def, Casa Bey

The elusive MC seals his comeback with a funky sampler.

Jamie T, Sticks 'N' Stones

Makes his long-awaited return with a typically addictive hook.
