You are most certainly entitled to your opinion, and I know mine is not one that a lot of people would agree with.
As for MS, I understand why Carrie decided to release it, and like when Kelly Clarkson released her album that everyone but her hated and didn't want released - I am proud of her for making that decision, even though she was probably asked to choose something else...but I still don't think it had any business being released as a single. Not because it was/is a horrible song, but because she had better songs to choose from on the album. SWISLY would have been a PERFECT choice, IMO...and I think that my frustration with MS stems from my annoyance that SWISLY will now most likely never see the light of day, and was for me, the best song on the album...and one of the best that Carrie ever recorded to date.
Awards aren't everything and Carrie has plenty of them, but I still would love to see her win Album of the Year, just once. And I'm still waiting on that day that I know will come where Carrie has 12 or 14 songs that will make up a piece of art that everyone will remember her for. I think the best is yet to come, and I'm looking forward to it.
