[SOLVED] Unknown Italian song

Hi guys, I'm gonna give as many details I can about the song. It's Italian 100%, sung by a man or a band, there wasn't any female voice. It should be a bit new, it's sure after 2005. I couldn't understand that much good the lyrics cause I heard it on the radio. Some of the lyrics were: ...e tu che cosa fai (or sth like that) and another was: ... ti prendero' (I don't think it was prendero, but sth ending in -aro'). I'm sooo desperate, I really wanna find this song. I hope that at least you've thought possible ones. Mille grazie:-)

It plays all the time on Greek radio.
