Why aren't FM's recordings in tune?

I just thought of this while posting in another thread and it's been bugging me.

One day I sat down at the piano and tried to figure out You Make Lovin' Fun from memory. I learned it in A flat minor, because that was the key I thought I remembered it being in. When I tried to play along with the CD it sounded like abosolute garbage, so I transposed what I learned to G minor, which would make more sense because I've read that Christine prefers the easy keys like G, C, F etc. Playing that song in A flat minor is a real pain in the ass. Once again, it sounded like absoulte trash in G. Tried again in G flat but that was the worst of them all. I've determined the only keys they could be in were in some in-between semi-tone key, which renders playing along to the CD's useless.

Had the same problem when I tried to play along to Morning Rain. However I played along with Never Forget and it sounded fine.

It just seems like the majority of their music sounds just a bit too sharp, and now when I hear the recordings it bothers me because my brain wants to hear it at the right pitch. I can still enjoy them but I wish I could like, retune the music. LOL

Any insight into this? I can play along with pretty much every CD I have except FM's. Most of their music is out of tune. Any insight? Thanks.
