I've had Ryanair play music once on a flight back from Rome last summer. I can't remember what it was, but it was just a background tune to a song, with no words. On my last flight with them (LBC-STN) they played thier own adverts over the radio, quite loudly.
Flying with BA, I have never heard the familiar tune, but accoridng to my sister they played it when she was lanidng at Phoenix last summer. They had it continue while disembarkation took place too. They may have played it on a recent flight of mine back from BUD, but the song may have actually just been going through my head from the expectation of them playing it.
