I am pretty much referring to music that you actually own in one way or another, not music from Spotify, Deezer, SoundCloud, YT (Music) or whatever provider you use to stream music.

I am a bit old-fashioned and I prefer to have actual ownership of the music. I have a bunch of vinyls, some physical CDs that I use for backup (basically I rip them again if I ever have a problem with the already ripped files on my PC - also saves time because I can skip the albums that I own on CD when backing up my computer) and that I also buy because they're cheaper, and finally I source the music from wherever I can find (mostly on Bandcamp when I can buy it). My rule of thumb is to keep .flac files on my PC and .mp3 on my phone, as the storage is lower - but sometimes the formats in which songs are available vary.

How are you keeping your music? Is it a digital or physical/analog environment? If it's digital, which is the format of your choice? Why did you find it better for yourself than the rest?
