Girl band 4Minute take no chances with their second album Hit Your Heart: the rising stars of the K-pop world stick to the sounds that made their single Muzik so hot. The album is filled with dance tunes and a blend of Korean and English lyrics. Opener Who's Next (featuring Beast) introduces the heavy beats and synthesized sounds that dominate the album. In Invitation, the girls urge 'everybody, anybody, move it, move it, let's go' - their call to dance is hard to resist. Bababa is another fun number that uses the nonsense title as a hook, a technique that has worked well for Lady Gaga. The success of the songs lies in rap and repetition - but this is also their downfall. No track stands out. The English lyrics are limited to catchphrases, but this soon becomes tedious. The songs are so heavily synthesized there is little chance for the girls' voices to shine. An abrupt change in approach saves the album from being a disc of likeable but forgettable tunes. The last track is a keys-driven number with drums and gentle strings. The result is surprisingly tender as the girls croon 'I will pray for you every night'. The girls seem to predict the future when they sing 'I am gonna be famous'.
