Key brings attention to 'the best cover' of f(x)'s '4 Walls'

SHINee's Key�is�a sweetheart! Not only does he go around listening to YouTube covers of his label mate group f(x)'s new song, '4 Walls,' but he also knows how to publicize a particularly good one because he appreciates talent!

TheRealDavidKim�posted an awesome cover of the song from earlier this month, but Key discovered it recently and posted a screenshot onto his Instagram so all fans of the song could listen to this version and appreciate it! �He even writes, "wow the best cover."

It's definitely a great cover with TheRealDavidKim's own personal flair - so listen above! He also covered other great K-Pop songs like iKON's "My Type" and Twice's "Like OOH-AHH."
