When I first heard that Girls' Generation Taeyeon, Tiffany and Ah Yeon were doing a cover and performance of "Lady Marmalade," I was frightened. Mainly because the song is extremely sexual, suggestive, and there are some high notes in the song. But fortunately, it was great and innocently sexy.

Pussycatdolls's "Button" is one of my favorite songs and Taeyeon, Gain, and Sunye's rendition of it wasn't too bad, not bad at all. In my eyes, Sunye is such a good, Christian gal and I forgot how well she can do do sexy.

SISTAR's Hyorin can sang! No one can ever hold a candle to the greatness and the legendary Beyonce but Hyorin's cover of "Best Thing I Never Had," is a great attempt.

Ailee's cover of Alicia Key's "Girl On Fire" is flawless. We get it Ailee, your vocals are insanely perfect!

Wonder Girls' lovely leader Sunye kills Josh Groban's "You Raise Me Up," at a concert in Hong Kong.

The video that brought Jay Park's career back into full circle was his cover of Bruno Mars's "Nothing On You." After his exit from 2PM, everyone waited patiently for his return and when he released a cover of the popular song from his bathroom in Seattle with his own twist to the single, fans around the world went crazy and the video went viral in a week.
