For me it's quite a small percentage. I've had my music on shuffle all day and most of it's just okay, or good even, but very few of the records i have do i feel a real emotional attatchment to. I'd say i've only ever really been in love with about fifteen records, the rest differed from stuff i kind of like but can't get 100% into, to stuff that's just okay, to stuff i don't even know why i bought/downloaded. Which records are you absolutely, even obsessively, in love with, and name them if you can be bothered...

All of them
Seriously, every single album i have on cd I genuinely love. Apart from Goo by SY but i haven't really listened to that yet. There are a few albums however (Grace, Ok Computer, Lateralus, Astral Weeks) that I have loved to a ridiculous point which means i've stopped hearing new things about the records and know every part inside out.
How?
do you not buy anything you might not like or are you extremely easily pleased?
I like having some bad records and some heroic failures... adds spice to the collection
I probably genuinely love about 20 records but i do also dislike Goo so ^5 on that
How many CDs do you own?
how many cds do YOU own?
eh? eh? EH?
Probably about 500
HW BOUT U?
PROLLY WAS 500
BUT I HAD TO SELL 150 / 200 COS IM POOR :[
I sell CDs I don't really like
that's economical!
i don't really get a connection with music like that
unless it's really moving post-rock or something.
