Can ya'll stop trying to defame PRISM? It's her best piece of work. Yeah the tracks are all over the show but it's ICONIC and FLAWLESS and "Legendary Lovers" and "Birthday" are better than 80% of Teenage Dream (the 20% being "Teenage Dream" and "Last Friday Night" - BYE!).
Prism has so many good songs in its collection but overall it doesn't know what it wants to be so that's why it's her worst album. Teenage Dream and OOTB really had some sort of narrative that you could follow whereas PRISM felt like it was trying to tell too many stories and by doing that, it told nothing at all..
