Thomas Golubić is the music supervisor for Breaking Bad.
You can find out more information about him at his website, SUPERMUSICVISION, which lists much of the music used in the series. Unfortunately, this site, like AMC's own site, has some erroneous information. For example, his site states that "Rompe" by Daddy Yankee was used in the episode, "". This is incorrect, the song, "Rompo" by Max One was used.
