It's lucky that I have to buy all this stuff, 'cos it's not only bookshelves I've run out of - my CD shelves are all full, too. Hundreds of the bloody things I have. (It's a bloody good thing I won't be working at ThoughtWorks' Holborn office - it's just too close to Charing Cross Road for all the great bookshops, Oxford Street and Berwick Street for record shops, and Regent's Street for the Apple Store. I'd be bankrupt in six months.)
I did love Help! I need somebody to sort my CD collection. It's a real problem. I've gone for grouped by artist, generally random otherwise - though I do have shelves specifically for jazz and classical. Err, classical and baroque. But there's a bit more grouping than that - solo artists are sometimes kept with bands that they've been in - Paul Weller with The Jam, Sting with The Police, Roger Waters with Pink Floyd, Thom Yorke and Jonny Greenwood with Radiohead, The Raconteurs with The White Stripes. I think you get the idea. ;-)
Naturally, I can never find anything.
And sorting by Genre? That way lies madness. I spent ages fiddling with the genres in iTunes, then just gave up and put 90% of it under Rock/Pop.
Anyway, Recent new acquisitions that I'm enjoying include The Noisettes, Get Cape, Wear Cape, Fly., Jamie T and Jonny Greenwood's Bodysong. Recent disappointments include The Good, The Bad and The Queen and the new Bloc Party album.
