Karaoke tracks with backing vocals are the gold standard for this song for several reasons:
The rhythmic complexity of salsa can be tricky; the backing vocals act as a melodic anchor to keep the singer on track with the tempo.
The chorus repeats "la la la la" frequently; backing vocals help maintain the song's "euphoric" energy even if the soloist needs a breath.
"Vivir Mi Vida" was a massive comeback for Marc Anthony, spending 17 weeks at No. 1 on Billboard's Hot Latin Songs.
