O Tú o Ninguna

"O Tú o Ninguna" ("You Or Nobody") is a song by Mexican recording artist Luis Miguel. It was released as the second single from his studio album Amarte Es Un Placer in 1999. The song was written by Juan Carlos Calderón and produced by Miguel. It became the thirteenth number-one song by the singer in the Billboard Hot Latin Songs, at the time, the most for any performer in the history of the chart. At the 1st Latin Grammy Awards, Calderón received a nomination for Song of the Year, losing to "Dímelo" by Marc Anthony. A live version was included on the album Vivo (2000), and in its original form was later included on the 2005 compilation album Grandes Éxitos released by Miguel in 2005.

The song debuted in the Billboard Top Latin Songs chart (formerly Hot Latin Tracks) chart at number 13 the week of October 9, 1999, climbing to the top five the following week. At the week of November 6, 1999, the song garnered 18.7 million audience impressions in the United States, leading to its peak at number-one for one week, 26 months after Miguel's last chart topper, "Por Debajo de la Mesa" in 1997, making him the performer with most number-one hits in the chart (13, not counting "Ahora Te Puedes Marchar" in 1987), surpassing Mexican singer-songwriter Marco Antonio Solís and Spanish performer Enrique Iglesias, each of whom had achieved 10 number-one hits at the time. With this number-one placement, Miguel accumulated 57 weeks at the top of the chart, tying with Iglesias. "O Tú o Ninguna" replaced "Dímelo" by Marc Anthony at the top of the Hot Latin Songs chart and was succeeded by "Llegar a Ti" by American singer Jaci Velasquez.
