The first few minutes of Birth Pains...

When I first heard it, it reminded me of the Besaid Island music from FFX... Kinda has a... tropical (for lack of a better word) feel to it.

So I guess you're not alone on this...
 
Haha, this is kind of odd as I played Final Fantasy 7 again when I first got Bath & Leaving Your Body Map and I listened to them all the time while playing that game so now I can't listen to those albums without thinking of Final Fantasy 7.
