If there is a radio station that plays English music?
It depends what type of music. These days I listen to Eska Rock, which is mostly English Language music. Many Polish bands sing in English anyway.
If you only listen to English music you'll miss out on some good German, Russian and Polish bands.
To my knowledge there is only one strictly Polish (music) radio station.
Your main problem is not finding English language music, but finding a radio station that doesn't repeat the same tunes every half hour.
