CDs all the way for me, if it's something I care at all about - I buy a lot, and am not averse to downloading releases from Bandcamp to burn them for myself either. I'll back up CDs up digitally (WAV and MP3) as well though. And if I don't really care about a release then I'm more than happy to just let mp3s stagnate on my hard drive But yeah, I mostly listen to CDs. And research stuff on YouTube. I do have some vinyl, but that was amassed for DJing rather than collecting purposes; and I no longer have anything to play it on. Shout-out to cassettes, the first cut is the deepest and all that... but I definitely don't listen to tapes any more.
