ER has the theme song title drop heard in the series finale of the show, And in the End, in 2009.

Likewise, Breaking Bad does this near the end of its penultimate episode, "Granite State", with the track "Dimple Pinch Neat" which starts out as something unrelated, but eventually transitions in the series' intro theme, becoming a Theme Music Power-Up for Walter. Notably, this is the only time said theme is actually heard inside an episode.
