The song was written and produced by Marc Anthony and Cory Rooney, and like the previous English single from Marc Anthony also a Spanish version was recorded, but wasn't included on the first edition of the album. Both versions of the track were very successful in the United States. The English version peaked at even higher than "I Need to Know", climbing to number 2 in the Billboard Hot 100, kept off from the top slot by "Maria Maria" by Santana featuring The Product G&B. It also spent seven weeks at No. 1 on the Billboard adult contemporary chart. The Spanish version ("Muy Dentro de Mi") hit No. 1 on the Hot Latin Tracks chart for 3 consecutive weeks. According to Anthony, he wrote this song for his then-friend Jennifer Lopez, whom he married soon after. This version was nominated for a Lo Nuestro Award for Pop Song of the Year, losing to "A Puro Dolor" by Son by Four.

The English-language version of the track received a nomination for a Grammy Award for Best Male Pop Vocal Performance, the second year in a row for Marc Anthony, losing once again to Sting with "She Walks This Earth (Soberana Rosa)", a collaboration for the album A Love Affair: The music of Ivan Lins.

"You Sang to Me" was included on the compilation album pLATINum rhythm, released on October 30, 2001 by Maverick Música. It is also included on the movie soundtrack for the 1999 hit movie Runaway Bride, winning an ASCAP award in the field "Most Performed Songs from Motion Pictures" for this collaboration.
