With only six days to go before the show’s seventh-season premiere, the mass exodus of American Idol alums from major labels continues: Katharine McPhee, season five’s runner-up, has parted ways with RCA after only one album, her self-titled effort from last year that debuted at No. 2 and had a couple of decent tracks alongside that absolutely horrific ode to strappy sandals. The album sold 366,000 copies. [Billboard]
