Karmin's debut title is not just the kind of cutesy thing we'd expect from these wide-eyed internet phenoms. It also introduces Amy Heidemann and Nick Noonan as legit pop stars, not just campy cover artists. Everything here is candy-coated in sugary beats and irresistible hooks, as if they've attacked the YouTube cover artist conundrum with a cotton candy blow torch. Heidemann's Minaj-ian, sassy-stoopid spitting and pop belt make even silly tracks like girls-night anthem "Too Many Fish" delectable. But without a little more substance, anything more than an EP might result in a tummy ache.
