These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Uta No Prince-sama
Awesome Music: The music is composed by Elements Garden, and some of the tracks definitely apply, like "CRYSTAL TIME".
Broken Base: For some fans of the original game the anime dumbifies the characters and loses the spirit of the original. However, there are also many fans who knew the franchise thanks to the animated series, and who prefer watching the guys interacting with each other than engaging in romance with Haruka.
Die for Our Ship: Haruka is a girl in an otome game. Three guesses as to what the rabid yaoi fans do to her.
Ho Yay: Plenty. Couplings include Ren/Masato, Natsuki/Shou, Otoya/Tokiya, etc.
Launcher of a Thousand Ships: Haruka. Considering she's the heroine of an otome game, she already has at least six good-looking guys after her; she can be paired with Otoya, Tokiya, Masato, Ren, Syo, Natsuki, Cecil, Hyuuga, Ringo, Reiji, Ranmaru, Camus, Ai... and the list goes on.
Les Yay: Haruka gets REALLY happy when Tomochika visits her.
The Scrappy: Haruka, for fans of the anime (mainly disliked for her generic personality) and Cecil for both game and anime fandoms.
The leader of Heavens as soon as his group appeared.
