I cancelled my Spotify account some time ago due to a band I liked at the time (Thank You Scientist) having their catalogue dropped making me realize that I do, in fact, own nothing -- but I was not happy about it.
During a trip back to my parents a couple of years ago I found an old CD binder of mine that was packed full of old music that I thought I had lost, so I took that home with me and started the slow process of ripping music to my hard drive. Foregoing MP3 I decided to rip them as WAVs since I have a big disk and a pair of Sony M4s and it was like a new sonic universe had been opened to me.
I have about 200 CDs in my collection now, a lot of them old ones that I did end up losing but repurchasing. There's apparently a niche enough market for them that some arbitrage can happen. For instance, using Amazon as a spot market I found a CD for $5 used at a local book store that sells for $40 minimum at Bezosland (Dance Gavin Dance - Mothership for those curious). My mom has also come in clutch, finding Drive Like Jehu - Yank Crime at some flea market local to her and throwing it into my Christmas stocking last year.
I can't stress the quality of the music with a good set of headphones and a lossless rip. And best of all I own this music forever.
I ended up messing up a lot of my CDs by constantly taking them in and out of cases and CD players. I still have my old Sony Walkman from back in 2003 as a reminder of the good ol days. I'll never part with that.
Now all of my music is ripped onto my media server as FLAC files and I take advantage of PlexAmp. I never have to worry about a particular artist being removed.
I am a huge archivist for these reasons.
Ditto, I love my Plex server. All of my media, thousands of CDs, DVDs and BRs available from anywhere. I even let family and friends use it, so I can share without having to give them physical media.
