I like her but she didn't progress much with Heavy Rotation.
It was like listening to one of her old albums, which made it a bit boring.
Not to talk about her weak first single IMO.
With that being said, cut her some slack, sales aren't the same anymore, so yeah, 150k is disappointing but it's not like everyone is selling millions these days and she took a long 4 years break.
Seriouly she needs to make better quality stuff like her old stuff.
