Wow, so terrible that you said terrible 6 times. Aside from that, I agree with you. She's also quite the diva, I heard.
Has anyone heard "Brokenhearted" by Karmin? I thought that was Kesha, but then I saw her on the Macy's Thanksgiving Day Parade (Carly Rae Jepsen also participated in the perfomances of the parade), and I later heard Kesha's new song "Die Young" (which kids will do if they do what she and other artists sing about in songs such as that). Karmin had previously covered several other songs of similar styles before releasing this original composition. I don't really like it, though... Other songs that I find annoying are "Moves Like Jagger" and "Payphone" by Maroon 5.
Other times, though, I tend to hate a song because of the subject matter discussed in the song, including "Set the World On Fire" by Fun, because it glorifies getting drunk and wasted. I don't get what's so fun about getting drunk and wasted, and when you're drunk in a bar, and you either pass out or start a fight, the police will carry you to jail.
While some of you may hate Justin Bieber, I hate Justin Timberlake. The "Sexy Back" song, which at one point I wanted to make a parody of (pertaining to Aqua's bare back in Birth by Sleep), is quite disgusting and perverted, and while his first solo album, Justified, was okay, his second solo album, Future Sex/Love Sounds (which "Sexy Back" comes from), was horrible. Both albums were somewhat perverted, but his second album was much worse. I liked him much better back when he was still with N*Sync, but now that he's gone solo, especially with his hip hop collaborations, I think he sucks. As for Justin Bieber, I would have to guess that some of you hate him because he's not "manly" enough.
