The thing I like about Taylor's albums (at least from the three I've heard so far) is that they are very autobiographical. They are like one big journey made up of different stories that all end up piecing together in a thematically powerful way. It isn't shocking that Her music is so acclaimed.
The best pop songs released in the past 10 years according to an international survey by a prestigious institute:
2005: Don't Cha
2006: Say It Right
2007: Umbrella
2008: Waking Up In Vegas
2009: Paparazzi
2010: Teenage Dream
2011: The Edge of Glory
2012: Diamonds
2013: Do What U Want
2014: This year sucked 4real
2015: Sparks
Anyone who disagrees with this list has poor taste. Gaga having the most entries, Queen of Pop tbh.
You can so tell Katy doesn't like Beyonce or Beyonce type artists. Her whole "Beyonce is God and I want to be her and roll around in her dirty underwear and lick the ground she walks on" shtick feels fake.
