Ash & We Are Scientists Washington Parks In which the two indiepop bands take a stereo channel each (Ash left, We Are Scientists right) to record a rollicking song about small-town life, in aid of multiple sclerosis. Great cause, great tune. Chris Salmon
Toddla T Fly Sheffield producer Toddla T closes his new album Watch Me Dance with this heart-tugging conscious reggae track, featuring a melancholy Ms Dynamite and the daydreamy harmonies of Jamaica's the Silvertones, who are reggae royalty. Caroline Sullivan
Dub Colossus I'm in Dub With a German Film Star Insistent percussion, heavy bass lines, wailing effects and Ethiopian-influenced keyboards. From the limited edition, (green) vinyl-only album Dub Me Tender Vol 1. Robin Denselow
