Hey Switezianka, what do you mean, do you like Doda better than Kazik, because i find Kazik a heck of a lot better, well at least for pop/rock genre but,larger selection of songs and better songs.
I think putting these two in one topic is a mistake. Kazik is an experineced musician who has been a leader of a few projects (Kult, Kazik, KNŻ, El Dupa), done Tome Waits songs, done a great album with his dad's songs, who writes thought-provoking lyrics and represents some intellectual level, while Doda is a girl who plays ****** music and earns popularity by appearance and scandalizing behaviour.
These are two completely kinds of music. Kazik makes music and Doda makes just mass entertainment. It's like comaping Jodie Foster to Paris Hilton.
