I've listened to this song a ton in the past couple years, and I never get sick of it somehow. It is perhaps ABBA's best song -- see the
Wikipedia article on the song, "
The Winner Takes it All". I've been on an ABBA kick recently after having seen
Mamma Mia! on stage, which was in incredible experience. It really blew me away and I had a great time. My only regret is that I couldn't see it a second time because I got food poisioning the day I was going to go see it again.
I tried to do a little Schenkerian analysis on this piece for fun, but I'll refrain from posting more on that until I finish the actual analysis I have due as a final project.
