i dunno if u noticed but back in 1998 to 2002 before Fergie joined the group, Black Eyed Peas used to have meat and substance in their music. And even Fergie's debut with Elefunk in 2003 was not bad at all. And it was also the album that got them out of the underground and into the mainstream. And then the substantial rapping began to disappear and was replaced with hooky rhythm like My Humps and etc...

And their new album is really all about nothing at all...

I wonder what other bands did this. You know those bands who used to be brilliant before they got famous.

This is just my observation so i share this to find if there are others who observed the same
