Which do you use? I use the first one.
CDs and CD's
If you're referring to the plural for CD (or most upper-cased abbreviations), I believe the modern style is CDs. We used to use CD's years ago, but this may still be a matter of style that can vary from place to place.
The possessive/genitive of CD would be CD's (as in "The CD's top surface was scratched.") I suppose the plural genitive/possessive would be CDs'??

I'm talking about the plural, not the possessive. For the plural, I use CDs.

I think ''CDs'' makes more sense, and fits with the normal rule that plurals do not take apostrophes.

CDs is the correct one. However, CD's is still accepted (as far as I know).
I don't like it, though.

The comma in "CD's" is used for clarity. The same goes for years, for example, 1960's. But a lot of people think leaving out a comma is more correct. It really doesn't matter one way or the other.

Why would you need an apostrophe in ''CDs'' for clarity? It's a plural, not a possessive or a contraction.

That's because plurals generally don't take apostrophes.

I skip the apostrophe because it may cause confusion with possessive constructions.
Another example:
Something like "the '60s" looks better to me than "the '60's".
But then we have counterexamples:
There are two As and three as in the password: "A1A2a3a4a5".
There are two A's and three a's in the password: "A1A2a3a4a5".
There are two As and three a's in the password: "A1A2a3a4a5".

In this case, it'd probably be better to say something along the lines of:
There are two "A"s and three "a"s in the password: "A1A2a3a4a5".
There are two As and three as in the password: "A1A2a3a4a5".
There are two A's and three a's in the password: "A1A2a3a4a5".
