1. Vinyl 2. MC (cassette) 3. CD 4. MP3/FLAC/digital etc. It is quite simple - choose how do you like your music and tell us something about it - why, how etc. You may notice I've added MC to the list, which is quite an overlooked format on most polls I've seen (this was supposed to be a poll, but I'm dumb and don't know how to make one - I'd appreciate if a mod/admin would do that for me). So go ahead, make my day. It'd be nice if you could explain why is the specific format the format of your choice.
