Beyonce always has some type of competition when her albums come out .
Taylor- steam will have run out, threat on the singles front
Lady gaga- might be competition but not at the same time .
Mariah- unless she has another EOM era , not scary
Britney- unless she has a circus type era, not scary .
Rihanna isn't completion on the album front, she's already out of the top twenty . And she has like a couple more singles on her album that could be hits .
