I wouldn't say hate, but ones i dislike are...
Nickelback - Can't stand the lead singers voice, music is fairly bland and typical of 00s "faux Rock".
Jennifer Lopez - Can't sing, steals and lip-syncs to other singers vocals on her songs.
Eminem - Vile lyrics, homophobic, constantly objectifies women, does anything for relevancy.
Ed Sheeran - Bland.
Lady Gaga - Unauthentic post-2013.
Miley Cyrus - Annoying also unauthentic.
Demi Lovato - Also annoying, Needs to log off Twitter, screams through her songs.
Dua Lipa - No stage presence, bit bland
DJ Khaled - No real talent, isn't a DJ, basically just says the same catchphrase at the start of every song ("We the best music", "another one"... And so on)
Drake - Somehow remains hugely successful despite having no real talent. He's a rapper who sings but can't rap or sing and doesn't write his own music.
Nicki Minaj - Requires no comment - although i actually liked one or two songs off her last album she has an awful personality.
Cardi B - Again requires no comment.
Kanye West - Once again requires no comment, but his most recent album was tragically awful and shouldn't have been released.
I don't agree that all modern music is rubbish, yes lots of the stuff on the radio is awful but there's plenty of good/great songs. It all really comes down to personal taste really, the current "mumble rap" that seems to be popular just now is rancid however. Even when it comes to modern pop music there is some great song, albeit i suspect some members would be scared to admit it in fear of damaging their masculinity...
