Music is another favourite of mine, and I buy CDs of those artists I like and usually try to get all their releases. My first CD was a secondhand one - Siouxsie and the Banshees - "Tinderbox" - since then I've added almost as many CDs to my collection as I have caches... I like the artwork that comes with physical recordings (be they vinyl or compact disc) and I try to avoid digital downloads as much as possible for this reason. I can't pick a favourite, I like my music for different reasons and for difference situations/moods so the best I can do is quote from an old Genesis song "I know what I like, and I like what I know"...
