This is barely even a song, let along a theme song, but for the sake of archiving, I have the full, albeit short opening sequence of Breaking Bad below. It is this Western-themed play on bongos and a steel guitar that accompanies the revealing of the logo.
No music credits yet are available, so for now this theme is unnamed and still without a composer.
There is also some talk about the song used on Breaking Bad promotional stuff. It has been answered though, and is known as the one that goes “whoo, whoo…” “Feeling the Moment” by Feeder.
