Julieta Venegas started off life as a Latin alternative star - a female singer/songwriter who happened to be mejicana.
Somewhere along the way, she became a big hitmaker. Mostly, this involved a big balloon and Julieta's accordion skills.... and this song, a huge hit in Mexico and on Latin radio in the United States.
So, her name should ring a bell by now. Recall that she wrote and provided background vocals to Monday's song, and also performed on one of Wednesday's songs.
She also did an MTV Unplugged performance that was really strong. This is the song with which she closed.... Even more than the studio version, this captures the true ranchero feeling that the song is supposed to convey.
Now, after all this, I'm going to tell you a little secret about Spanish-language artists in general, and Julieta Venegas specifically. This is a performance she did for the NPR station KCRW, on their popular show Morning Becomes Eclectic. She performs Me Voy at about the 19:45 mark, but I encourage you to take some time and listen to the whole thing. Notice that she proves that she is multiinstrumental - she's playing keyboard, and not accordion, in this version.
And she speaks perfect, unaccented English.
