Same here. When it comes to music, I don't care about the lyrics, so it could be in Swahili and I might still enjoy it. None of my own music compositions have lyrics, for that matter; they're all instrumentals.
I listen to the Voice of Greece every evening, too, because I'm especially fond of Greek music. When poor propagation makes it hard to hear, I go to one of the Greek stations on the internet that offer audio streams, which I access in my media player. Sometimes I get curious enough to look up the meaning of a title if it shows up in the player's title bar. One thing I've learned is that if you hear the words "agapi" or "agapo", the song is a love song, as most of them seem to be.
