Muse are not cool. For a minute on leaving the tube station I did think they'd broadened their appeal quite dramatically before realising that a fair section of the people around me were heading to Giants of Lovers Rock show also at the O2 complex last night. But no, their audience, judging by those heading for the main arena, are a fairly even split between hyper-mainstream V Festival demographic and slightly misshapen indie/goth kids, not really much more rock'n'roll in demeanour than, say, a Coldplay crowd, but very dedicated.

First a confession: I've never been a great fan of Michael McIntyre. He's a nice bloke for sure, works at his craft and is a slick performer with a huge following, both live and on television. Plus - and this is one of the best compliments I can pay to a stand-up because it's a difficult skill to pull off - he's one of the best MCs in the business. But I can't get past the feeling that some of his material, to borrow shamelessly from another context, has the whiff of previously used about it.

The rise of Korean pop (or K-pop, for short) in Europe has been steady; conceivably, all that’s needed for the common or garden music fan to become enraptured is one crossover artist. Countless new acts sprung up following the first wave of K-idols - G.O.D., SES, H.O.T., Shinhwa - and a new one continues to appear almost every week, unveiled after years of training. They often live in boarding schools with strict diets and no guarantee of success, a regime for which the Korean culture industry is estimated to have generated some $3 billion. 

Nicky Byrne, Shane Filan, Cian Egan and Mark Feehily announced they were retiring Westlife in October 2011, but not before this final farewell tour. It proved to be an opportunity to roll out the red carpet for Facebook-status emoting and self-pity about entering the post-fame abyss. The endless video clips squeezed in throughout their two-hour set (no sign of Brian McFadden, who left in 2004) must surely have exhausted even the most devoted attendees at some point during the evening.

One image remains stuck from Watch the Throne's second of five sold-out nights in London; it’s a song-long vision of Kanye West and Jay-Z – aka J Hova or just Hov – sat side by side for Hov’s “Hard Knock Life”. Hov’s words fell out of his mouth seemingly effortlessly as the track's structure emerged while ‘Ye sat in a silent, contemplative stoop - his dripping sweat and jewellery making him look post-marathon mid-set.

Often it can seem the sheer struggle of early reggae gets lost in all that happy, spliff-smoking Rastafarianism of Bob Marley's Legend. For one-time label-mate Jimmy Cliff, however, there was never any sense of “every little thing's going to be alright”. In the 1972 film The Harder They Come, he played a musician forced into crime and eventually shot by the police. And as a singer-songwriter, over a 50-year career, he has sung of injustice and hope. Last night, in front of a rambunctious indigO2, a 64-year-old Cliff showed he has absolutely no intention of mellowing.

Drake’s routine is divisive; he’s attracted hip-hop’s most loyal following in a somewhat unconventional way. By using self-doubt as his signature complex, he’s taken something traditionally uninteresting and made it his calling card. The cringe factor in his lyrics seem, from the outside, best suited to an album at the tail-end of a career, but that’s without considering his charm, his astute ear for a chorus, and how unashamedly, loveably contrived and cheesy his whole shtick is. 

It's awards season for the music industry, and no amount of complaining, ignoring or pointedly watching BBC Four in protest is going to stop the BRIT Awards from ordering in a few thousand servings of homemade tomato chutney and crostini to be laid out for the insider guests gathered at the O2 Arena. It's their once-a-year big chance to let their stars try and demonstrate their USPs in their winner's speeches, for starters. However in 2012, it seems that there's all too little that's unique about many of them - in particular their "love" for their fans. 

It would always be a risk putting such a gossamer Christmas charmer as The Nutcracker into a gargantuan Mammonite cavern like the O2 Arena, where magic only counts if it rings loudly in the coffers - car park £25! programmes £10! As with the Royal Ballet’s Romeo and Juliet last June, Birmingham Royal Ballet have put up a cinema screen to enable thousands of viewers far away to catch what looks dolls-house-sized in real view.

Call it an absurdly grand gesture if you like, but Manic Street Preachers' decision to bow out of live performance for a while with a gig in which they would play every one of their 38 singles had to be admired. It certainly had an all-or-nothing rigour that Richey Edwards would have endorsed. But would James Dean Bradfield recall all the words? Would Nicky Wire's knees survive all of that sustained bouncing around. Would piledriving drummer Sean Moore wear a hole in his skins? These and more questions were answered during last night's frequently stunning gig.
