CDs Vs LPs

Kosst
Not quite sure why you are so stuck on this but as an,old fart here I can you this.
NOBODY I know would ever differentiate a CD length by tacking on terms like lp or ep. Not saying somebody somewhere does not do so just have never heard it used myself.

Now in the vinyl world it is VERY common to use the terms lp, ep and single to differentiate between the different durations of the vinyl, I hope we all understand those differences!

To my ears a CD is a CD no matter what its duration.

Just my opinion......

In my experience, there is no such thing as a "long play album." This terminology is being confused with the correct "long playing record." An "album" is usually considered the volume of work that is recorded on the record or CD.

After the large diameter, high speed 78rpm records came the 45rpm - a smaller diameter record that was typically one song on each side. Then technology allowed us to play recordings at 33rpm on a record of much larger diameter with good fidelity. Those vinyl discs became known as "Long Playing" records (or "LP’s") because you could get (typically) five or six songs on each side.

Ralph, It is possible that vinyl does not sound good to some people, just as some people will not listen to digital in any form, even Lps that have digital anywhere in their lineage.  We all hear differently.

Quick interrupt. What’s really required is a trade off study using criteria and weights assigned to each criterion. Then you add up the scores for each criterion times it’s weight and the one that has the highest grand total wins. There’s really no other way to do it, it gets way too subjective and loosely goosey. Pick your own criteria or decide on a list. Let’s say Resolution, Dynamic Range, tonality, frequency extension, bass performance and transparency for starters. Weight them any way you want to.

Uberwaltz,
Vinyl has pretty much been an obsolete technology my entire life. If a music store carried it, they'd have maybe 30 or 40 albums in the back corner. Good old fashion tape is what I grew up listening to. I'm quite sure I've never heard a vinyl record broadcast on radio. I like tape. 
Having grown up in an era where vinyl basically didn't exist, terms like LP, EP, and Single most certainly persisted completely independent of the recording medium. I've bought plenty of LP, EP's, and singles on tape and CD. Those are the ONLY ways I've ever bought hardcopy music. I don't think anybody 40 years old or younger associates LP, EP, or Single with the diameter of a piece of plastic. Calling anything that comes on a disk of vinyl an LP strikes me as having the same logic as calling my HP printer/scanner/copier a Xerox machine. It's an antiquated misuse of terminology that dates the user to a generation born before about 1970.
