Cheryl Cole, Bruno Mars, Rihanna, Beyonce, Avril Lavigue, Michael Buble, Eminem, Adele, Usher, Michael Jackson etc. There are many еще but I don't feel like naming them all.
Lately I've been еще into bands though. Such as My Chemical Romance, Blink-182, Paramore, Embrace, Bullet For My Valentine, Bon Jovi, Metallica, Radiohead, Blue October, The Beatles, Fall Out Boy, Paradise Lost, Linkin Park, Оружие n' Розы and many many more!
Britney Spears- I know, I know unpopular opinion, to be honest I hated her during her 'hit me baby one еще time' phase. But I oddly became endeared to her post-meltdown, can't even explain it but she's my Избранное now.
