With the lightning speed of online delivery, there is still masses of time to select the best and most enjoyable presents for Christmas, thanks to the taste and wisdom of theartsdesk's pack of writers.

The couples profiled in the series included the likes of Zelda and Scott Fitzgerald, Sartre and de Beauvoir, Monroe and Miller, and remoter figures from the German 19th century. Pop hadn’t made it onto the list, though I learnt, once embarked on the commission, that Lennon-Ono had been considered but no author found. In 1996, I happened to be in the right place (Berlin) at the right time.

Luxembourg's musical landscape has few claims to represent the Grand Duchy itself. Most of Luxembourg's Eurovision entries weren't actually from the Duchy, as there was little local music to draw on. So Belgium's cod punk-gone-blando Plastic Bertrand became 1987's entry (with “Amour, Amour”). In 1965 Luxembourg won Eurovision with France's France Gall's “Poupée de Cire, Poupée de Son”, a song written by her countryman Serge Gainsbourg.

For hundreds of years now the island currently known as Sri Lanka has had a thriving musical culture (or cultures, not to politicise the issue). There’s been folk music for as long as there’ve been folks. The various strata of society have refined their ceremonial music, be it sacred or profane. Each ethnic group in each part of the island has hived off its own sub-genres over the centuries. And in the colonial era (eras) a whole new batch of influences arrived, fully formed, ready to be adopted wholesale or adapted and integrated for local use.

Nobody really knows what CMJ stands for, but then few of New York’s residents know of the five-day music festival’s existence either. Involving more than 1200 bands and 75 cross-borough venues, CMJ is for the real music fans - dare I say, geeks even - as the smallest, newest and most unlikely of musical acts enjoy the opportunity of a truly open platform for industry professionals, bloggers and downtown hipsters’ appreciation alike. Closest comparisons include the Edinburgh Fringe and Austin’s South By South West which happens in Texas every spring. But this is, after all, unique New York and CMJ is a truly NY event: non-stop and all night, featuring yellow cabs and mean door staff.

As the London Jazz Festival approaches, it's an unlikely fact worth noting that some of the bestselling instrumental jazz records of the last few years have been from Ethiopia. Ethiopian jazz composer Mulatu Astatke, now 66, is the best-known practitioner and enjoying an Indian summer. A key feature of the 2007 The Very Best of Éthiopiques compilation, once heard his music is not easily forgotten.

The music of Sibelius might speak of Finland, its unpopulated spaces, vast inland lakes, semi-Arctic climate and long, dark nights, but the annual Lost in Music festival brings together a bewildering array of Finnish bands and singers that range from rockabilly and ska to introspective folk and – of course, the national staple – heavy metal.

McDonald's (the hamburger people) are rarely acknowledged for their contributions to the arts, but without them we may never have witnessed the meteoric rise of composer Eric Whitacre. When he was 14, he heard a casting call on the radio for a McDonald's TV ad, persuaded his mother to drive him into Reno, Nevada to join the throng of hopeful teenagers, and ended up making a brief appearance in the "McDonald’s Great Year" commercial.

Maybe I hadn’t been paying enough attention. It was only at last year’s Children in Need concert, broadcast on prime time which featured the great and the good of British pop that it finally sunk in just how huge Muse have become – they were there appearing with Sir Paul McCartney, Take That, Leona Lewis and Paolo Nutini. Weren’t Muse the alternative Radiohead-lite band from Devon who sing politically loaded and enjoyably paranoid lyrics against the system and all it stands for?
