So, I thought I had a fair idea of how to tell what key a certain progression is in. If it starts and ends on the same chord then it is In the key of that chord. Or whichever chord gives that feeling of resolving the progression (which is always gonna be the last chord) is the chord that tells you the key. Am I right?

Well I've got a new problem on my hand. Let's say you have practically two different progressions in the same song - a different progression for the chorus and verses, for example - how do you tell what the key of the entire song is?

Let's say the verse progression is: Am/G/D/C. So this progression would be in the key of C because the progression resolves on C?

Now let's say the progression for chorus is: C/Am/F/D. This progression is in the key of D?

Keep in mind that those progressions are part of the same song. How do I tell what the key of the whole song is when both progressions are in a different key? I'm sure I'm wrong somewhere along the lines, but as of now, I'm confused.

I guess I could solo in the key of C for the verses and then in the key of D for the chorus.
