how do you get it from computer to the game, though?
download the audio to pc , copy to a usb stick , plug into xbox or ps3, copy files onto console hardrive.
ive been looking into the creation center and it isnt excactly what i thought it was.
its a 'create a team' option for offline/online single play.
create a team full of mates or an all time everton 11 , england 11 , popstars 11 , pornstar 11 etc (think sensible soccer

) .
the badges , kits , team names , stadiums and players are customisable but you cant upload images (so you cant use the g.o.t badge or use proper player faces).
created teams can be private or made public for others to download. you can also download other players and teams created by other people.
online clubs sounds like its changed slightly aswell .... its now 11 vs 11 + your stadium starts at 10,000 but grows in size as the club gets more successful.
getting into a club match is also quicker + they have added a cup competition to go with the league.
another thing ive come across .... go to game settings and turn the analogue sprint on .... it changes the feel of gameplay and is awesome.
