Similar to yours, solium, to concentrate on my existing (large) collection rather than to continue buying scores. I've cut down these last few years (buying classical works in precedence) but still buy unknown (either films or scores) works just because they are available.
And then I find that so many of these scores rarely get a second/third play ... so I'm planning to update my hi-fi (pre-amp) ... and listen to all (well: many, at any rate) those scores that get overlooked.
Of course, there will be the odd purchase ... any new John Barry releases on the schedule ... please!
I think I'll try to rekindle my interest to the obsessive level it was at for about thirty years of my life. It has since dwindled, but I was happy back then in my geekdom. After that I tried to become normal and pretend I was interested in other things, but it was just a show for other people.
Still, I'm not sure yet. Just as well I've still got a whole month to make up my mind.
While that number is shocking, suddenly I don't feel so bad about all of the money I've wasted on crap over the years.
However, I believe even your 20-CDs-a-month habit pales in comparison to another FSMer who used to post a veritable grocery list of stuff on order every month. That guy bought Goldsmith releases like they were eggs; easily a dozen a month.
I'm going to continue to be picky as hell with buying stuff and focus primarily on albums that are 100% orchestral. Thankfully with Spotify I can avoid buying new film scores blindly and getting stuck with a dud I won't listen to again. Samples have been the way I decide what to buy for many years now and it usually has worked out quite well.
