Bruno Mars looks back on a costly mistake in “When I Was Your Man,” a new song off his sophomore Unorthodox Jukebox LP due December 11. The R&B singer croons about a past love interest he lost to another man after not treating her right. Definitely a song listeners can relate to, as Mars bares everything with his piercing voice over the sounds of a piano. You can purchase the song currently on iTunes.
