Good topic, I like the positive attitude. I was just thinking the same thing the other day when re-listening to the full album.
On a personal account, however, I seem to have a problem with 'Some Girls', as I heard the early demo by Bebe Rexha that sounded just like the finished Madonna song. This is why I can't really get into this track. Madonna's voice also doesn't sound like hers. It is an altogether very enjoyable song though.
Tracks such as the indie genie that is Gang Bang, the witty chemical disco of I'm Addicted, the delicious Love Spent, the Orbit-meet-the Beatles I'm a Sinner - and of course the most heartfelt among Madonna's late ballads, Masterpiece, all give the album some real dignity.
I even started to appreciate Superstar after it was issued as a single in Brazil (I loved the fan-made artwork).
Turn Up the Radio is a banger, let's say it - and I uber-ADORE the MIA rap on GMAYL.
That said, MDNA remains easy pop music, probably fabricated in between thousand other projects (i.e. the W.E. film, the Superbowls), which might justify the so-many fillers (i.e. I Don't Give A, the already mentioned Some Girls, and all the bonus tracks minus Best Friend, which I find moving)
The CD cover was amazing and the tour did fantastic though - and that's all that matters really. Lol.
