What's your motivation for collecting ?

Hi ! I've recently discovered this subreddit and am super excited about collecting CDs.

I see some people on here with incredible collections of 1000+ discs, and I just wanted to know what people's motivation is for collecting loads and loads of music. Do you collect CDs because you love and listen to every single one of those albums, or is the charm of CD collecting just possessing as much physical music as possible ?
