I remember the Oracle said that he/she doesn't like Speed of Sound, for example, so it's not like he says everything is good. As for the Rihanna thing, the song was written with her in mind. The Las Vegas thing could've happened in 2008/9, they didn't say when it was. I'm sure it sounds better with female vocals since it's a story between two characters. But I think that maybe Rihanna is not a good choice. But also, please wait until you listen to the song. Obviously the Oracle works with the band, so besides being a PR/marketing person he knows what they're doing, how the album sounds as a whole, etc... Just stop complaining so much before listening to the full album, I think that listening to individual songs won't help to understand the whole in this case...
