A lot more than I'd like to. I buy CDs, DVDs, magazines, I go to concerts, buy goods when I go to concerts, go to see movies etc. Honestly I'm scared to count it. Last time I counted on how much I've spent on CDs was in 2011, and I was up at ~1400 USD. And my amount of CDs has more than doubled since then.
And that's just the CDs. orz
