The theme song of AMC's hit crime drama Breaking Bad was a moody instrumental piece that was put together by the series's composer Dave Porter, but since upcoming spinoff series Better Call Saul is said to have a very different kind of energy to the original series, it makes sense that it would also get a very different kind of theme song.

Although Breaking Bad is highly recommended viewing, newcomers probably won't need to have seen it in order to enjoy Better Call Saul, since it's a series that, in part, focuses on the life of sleazy lawyer Saul Goodman before he met Walter White and Jesse Pinkman. We're still waiting to see a full trailer for Better Call Saul, since the only thing AMC has revealed so far is a couple of short teasers, but now the network has unveiled something that's possible even better than a trailer.

Porter has teamed up with Adam Dornblum and show creators Vince Gilligan and Peter Gould - as well as country singer Junior Brown - to create Better Call Saul: The Song, a catchy new tune that encourages criminals of all flavors to contact Albuquerque's least scrupulous attorney. The music video includes a few new bits of footage, including a shot that shows a billboard for James M. McGill, Saul's real name and the one that he operated by until he changed it to something more Jewish-sounding, "for the homeboys who want a member of the tribe."

It's unclear whether this is the actual theme song that will be used when Better Call Saul begins airing in February next year or whether it's simply been created for promotional purposes, but it's certainly memorable. Better Call Saul will see Bob Odenkirk reprising his role as Saul Goodman alongside Breaking Bad regular Jonathan Banks, who plays Mike Ehrmantraut, and Breaking Bad actor Aaron Paul has said that he's also had serious talks about potentially appearing in the series.

Better Call Saul will reportedly take place before, during, and after events in Breaking Bad and, according to the showrunners, starts out as the story of how and why Jimmy McGill became Saul Goodman. One of the clips from the new series shows him telling people that he doesn't go looking for guilty people to represent (something that has definitely changed by the start of Breaking Bad), so Saul may end experiencing a similar character arc to that of Walter White, who started out as a chemistry teacher and family man before becoming a meth kingpin.

Better Call Saul premieres on AMC in February 2015.
