Less than 1! I doubt I buy 6 albums a year to be honest, so far this year has been Elbow at Abbey Road (disappointing sound quality, how annoying), Eli "Paperboy" Reed, twice (once on vinyl, dreadful sound quality, so bought on CD, which wasn't hugely better to be honest), Glen Campbell's latest, on vinyl, haven't got round to listening to that yet, and errr, oh yeah, Tubular Bells, CD, second hand.
So 4 in 5 months, that's actually more than I thought! Trouble with music for me is I don't really know what I like, I know what I don't like, so I don't buy it, but finding stuff I do like is difficult as it doesn't tend to get played on the radio.
That's it. I'm unbelievably fussy when it comes to buying anything like that, I'm the same with books, I stick to the same authors and it takes an awful lot for me to try anything new.
I haven't bought a DVD since the middle of last year as I decided I'd wait until I had blu-ray. I'm still waiting!
