4Minute's resident rapper HyunA has been chosen to be featured on Navi's latest track titled Wasteful Tears. After much persuasion from her peers, Hyuna had agreed to collaborate with Navi for this track. The song is very upbeat and showcases both females' natural abilities in their respective singing areas. The mastermind behind this track about a woman refusing to forgive her unfaithful man is none other than Jo YoungSoo, the man behind Navi's previous hit "Heart Damage." While I prefer "Heart Damage", you guys might like this track more. Check it out right here: cr. XxtenerifexX Thanks to j.nguyenn for the tip!
