Sometimes when I am alone in my home I sneak upstairs and pull out my 12" DISCO single play Lp's
You can still find some of these on CD...."Flashback Faves" and "Retro Remixes" and such as Duran Duran "Strange Behaviour"...and yes the sound was awesome on those 12" singles and you can rediscover some of that magic on these CD's (I had a huge 12" 45 RPM collection in the days before CD's - and these sounded way better than how they mastered standard LP's - often huge dynamics - love the sound of most of those)
Anyone who wants to dabble in this - simply download Grace Jones "Slave to the Rhythm - Hot Blooded Mix" from iTunes burn it to CD audio and queue it up....amazing sound even from a compressed file that makes a mockery of modern recordings!
