Avril was obviously supposed to release the 5th album under Epic but seeing the hit potential of WYWH have delayed the adds date until November to try and get the holiday sales for GL. Epic records is not a good label guys, but it may become a good one with the direction of LA Reid.
Also it seems they have split their artists up into the ones who want creative control and the ones who will be controlled by their label;
RCA:
Christina
Britney
Epic Records:
Avril
P!nk
Ciara (

@ her still having a record deal)
