At one level the day of the single is gone - the 7-inch, the CD, the physical format - and yet, at another it's more relevant than ever. Sure, any track can now be downloaded from an album and hit the charts but singles, downloads - chosen representative songs - still give the best snapshot of what an artist is capable of. With this in mind, theartsdesk gleefully tucked into the latest batch of releases which includes Depeche Mode, Arctic Monkeys, pop, rave, folk and a whole lot more besides.

Hip-hop soul, chart rave and Balearic beach-pop with a 1990s flavour, synthesiser-led space-rock, a localised Goth-electronic revolution, Kenyan Kamba beats, an eccentric attempt at bringing opera into pop, and vibrations from dubstep's deep roots. As ever, theartsdesk's singles round-up takes you round the houses, up some dead-end alleys, down the docks and along sweeping avenues you never knew existed, hopefully dropping you home exhausted but happy with a selection of strange and evocative new music in your pockets. We aim to please.

One of the most powerful things about the dubstep movement – aside from the monumental sound itself – is how its rootedness has provided a platform for a generation of artists to launch out into other things from. The spaciousness, drama and flexibility of the template has allowed maverick producers like Mala, Shackleton and Kode 9 to create their own unique sound worlds that bridge the gap between clubland and the avant-garde, far more than, say, drum'n'bass ever did. And now Bristol-based producer David Corney can be added to that list.

There's something about this album that feels as if it's already existed for a long time. Full of post-apocalyptic images of smoke, dust, decay and weakness, and themes of struggling individuals and implacable political forces, it thematically fits with the works of a long line of acts who positioned themselves against the fear of nuclear armageddon and the seemingly immovable Conservative government in the 1980s. Its mix of Caribbean-influenced soundsystem culture and dub poetry with an edgy alternative experimentalism, too, harks back to the post-punk genre collision of Dennis Bovell, On-U Sound, Renegade Soundwave and the like, 25 or more years ago.

This month, what's on offer in theartsdesk's Singles and Downloads veers towards the fresh and new rather than the tried and tested. We'll always chew over whatever's out there and right now these nine tunes speak loudest. Starting with carefree New York electronic punk frollicking, we also take on violent grime, Sixties-style guitar pop, Brit-pop hip hop, uncategorisable grunge cabaret and multifarious flavours of dubstep. Dive in.

Katy B has something of the everygirl about her. Part of her appeal is that, unlike Ke$ha, The Saturdays and so many other female pop stars, she hasn't embraced pole-dancer chic, nor does she appear to be gagging to be spread over the pages of Heat pondering her love life, her diet or her cleavage. Katy B is a 21-year-old from Peckham who looks like a 21-year-old from Peckham.

Googling for academic articles about Britney Spears is one rabbit hole I've managed to avoid falling down thus far, but one imagines there are reams of the things. From demonically driven Disney child star via pigtailed Lolita and sex-droid air hostess to shaven-headed loon lunging aggressively towards her public through the paparazzo's lens, she's provided no end of provocative and iconic images, and stirred up all kinds of problematic issues around post-feminism, celebrity and voyeurism, while remaining an odd non-presence at the centre of it all.

Avant-garde art, by its very nature, always treads a fine line between the sublime and the ridiculous, and between entertainment and alienation. Thankfully this is something understood very well by the joint curators of Friday night's show at the Vortex Jazz Club: Baron Mordant of the Mordant Music record label and Jonny Mugwump of the Exotic Pylon website and radio show. As the names perhaps suggest, these are people versed in the potential deep silliness of what they do, even as they take it very seriously indeed – and their event certainly ranged far and wide between the weird, the wonderful and the out-and-out wrong.

James Blake's "Limit to Your Love" was a bolt out of the blue at the end of last year, perhaps even a quantum leap in soul'n'bass culture in the same way that Massive Attack or Roni Size once were. This fact was swiftly acknowledged in various New Face of 2011 polls which Blake started cropping up in.

This month we have some unjustly hyped rubbish electro-pop, some unjustly ignored brilliant eletcro-pop, some postmodern retro-disco, some dubstep, some grime, some sampledelic New York punk, and, at the top of the pile, one of Britain's brightest young actors proves he's equally adept on the microphone. Thomas H Green and Joe Muggs plough loudly through the lot with glee and the odd barbed word.
