All of the above.
I’ve got plenty of records, including plenty of 7” singles and 10” EPs— tons of Zappa and King Crimson related stuff as well as oodles of power pop, new wave, and 00s-10s Aussie rock, just to make a few. No idea how many records I have, but it’s more than enough to fill 10 IKEA Kallax slots.
I’ve got a ton of CDs too— mostly again, Zappa, King Crimson, and other Prog Rock acts (I buy a lot from Moonjune Records on bandcamp), but also plenty of just about every kind of music. Lots of box sets (including a handful of the 20+ disc King Crimson boxes) and a decent number of DVD-A and Blu Ray Audio discs too. I might have a few dual-format SACDs too, but I’m not pretentious enough to own an SACD player.
Plenty of download purchases too, primarily from Bandcamp and Qobuz, as well as whatever sites artists are using to sell their Soundboard mixes from live shows I attend— I’m a fervent live audio collector, especially when it comes to shows I’ve attended. I’m also obviously a big fan of free downloads, and I’ve downloaded tons of Zappa live shows, Ween concerts, demos, and raritities, etc. over the years. I also buy a ton of downloads from the DGMLive site. I may or may not also have some recordings that I may or may not confirm to exist (pshhh… bootlegs of notoriously anti-bootleg bands? No way!)
Streaming is definitely the easiest for general listening though, so I do consume a lot of music via the very means I hate so much— Spotify.
