I'll certainly give it a listen and say if I like it or not... but the whole list of names is just off putting, Will.I.Ams songs seem to sound average and going off Rihannas previous collaborations, they always sound quickly thrown together.
That Princess of china track with Coldplay being a perfect example, it sounded extremely dull. I think people just throw the names in hope that people simply buy it off that and I remember last month hearing Chris Martin on radio saying that it's "the way forward for music", he made it sound like it wasn't anything to do with the actual song, but he was hoping Rihanna's fanbase would take note and buy the album... surely when they write these songs, they realise that it's actually more difficult then writing for the one, as they have to take into account who's voice is going to be on it.
