I think the only song off of 1989 that truly deserved to go #1 was Blank Space. It has a catchy melody, clever lyrics, and is all around a great pop song.
Bad Blood is one of the most undeserving #1's ever, it is EASILY Taylor's worst song in her entire discography. Style is so damn monotonous and drags on way too long
Shake It Off is what it is. A catchy, stupid, feel good song with not a lot of substance but it did its job so good for it I guess
Speak Now is still her best album.. Taylor writing songs all on her own is so much better than her writing with Max Martin. I really, REALLY want her to stop working with him, her original iconic writing style is so much better.
