Checkout this cool cover of Love on Top by Leroy Sanchez. This is one of the best cover so far from all that I heard. Love on Top by Beyonce is one of the most challenging song for all singers out there because the range of this song is getting higher and higher. And so, I like this guy for singing this song perfectly.
I really envy man with a good voice and especially those who can play with their falsetto. Other male artists I enjoy listening to (and really have good falsetto) are Lawson, Maroon 5, The Script, Justin Timberlake, Bruno Mars, and Jesse McCartney.
