Missing greatest hits

I have a pet peeve. There's little to nothing I can do about it, but it's there. I hate when an artist has multiple "Greatest Hits" albums, but none of them have all of the hits I want. The latest culprit: Alice Cooper.

The three songs I want together are: "School's Out", "Love's A Loaded Gun", and "Poison." After a long time searching, I found 1 double-disc set that had studio versions of all 3 songs. But guess what? It's from an bootleg Russian label! Doesn't exactly feel right buying it, and as it is, there's only one pricey copy available that I can find.

Sure, one might think "maybe he's got so many hits, you can't fit them all on one CD!" And you'd have a good point, if it weren't for the fact that there's a 4-disc set that has lots of his songs I've never heard of, but completely omits "Love's A Loaded Gun," which was even released as a single.

And then you might counter with, "but perhaps that collection was on a different label than the original album, and they couldn't get the rights." Usually a very valid (but annoying) point, but then why are other songs from the same album (specifically, "Hey Stoopid") on the compilation?

If feels stupid to buy two different "best of" albums to get all 3 songs (hello redundancy!), so if I enjoy the rest of his music enough, I'll likely buy the 3 original albums they came on, or I'll sit this one out (la, la, la, I can't hear you, Mr. Digital Downloads).

To note: For the record, I had a similar issue with Salt N Pepa, and I bought all the albums, and it turns out I really liked all of their stuff. Here's hoping I luck out again.
