So finally I listened to 
Red  
I love it, (of course 

).
But seriously it really showed her diversity, and I find the sounds and genres she covered ensures that anybody, even people who are new to Taylor, would find at least a few songs that they enjoyed.
The collaborations were okay, the Snow Patrol one is currently my least favourite track 

  But the Ed Sheeran one is actually pretty good.
'The Moment I Knew' is probably my favourite song off of the entire album, and I wish it was more than a bonus track (same with 'Girl At Home')
Overall I'd give it a 
9.1/10
