Listened to Judas about 4 times now and it is already stuck in my head. BTW was ok, but nothing on what GaGa can do, but Judas, now that's what I want! In love with Judas!
And metro? As in the one at train stations? We get those in the UK in London mostly I think
I can see how 'juda ju da da' is like 'ra ra ah ah ah roma roma ma' from Bad Romance but she has a habit of repeating syllables in words in her songs. Even 'po po po poker face' and 'papa papa paparazzi' I think it is just one of her signature things! She isn't really a huge fan of not singing for ages to have a musical bridge, especially live she just wants to sing and sing and sing and fill the song!
