The Sopranos has a nearly perfect opening title sequence, featuring Tony Soprano driving through New Jersey, accompanied by the song "Woke Up This Morning" by Alabama 3.
However, creator David Chase initially wanted a different song, one that would have explicitly laid out the show's themes, but would have been a terrible choice.
David Chase could have ruined his own show by choosing Elvis Costello over the Alabama 3.
Luckily, the final choice of "Woke Up This Morning" resulted in a more subtle and soulful introduction to the show.
Author's summary: The Sopranos almost had a disastrous main theme song.
