"Miss Me So Bad" is a song recorded by Puerto Rican band Son by Four. It was released as the lead single for Purest of Pain. It was written co-written by Diane Warren and produced by Ric Wake with the Spanish version being composed by Omar Alfanno. Richard Torres of Newsday unfavorably called it a "Backstreet Boys reject". RS Murthi writing a negative review album stated: "Such things as You Are Beautiful, Miss Me So Bad and Purest Of Pain will probably make you realise how harshly you had judged someone like Barry Manilow - compared to his dribble, this really sounds quite soulless". The Spanish version, "Cuando Seas Mia", served as the main theme for the telenovela of the same name.
