As we saw Walter White (Bryan Cranston) – bleeding and near death – back in a lab one last time, he had just the song to send him off. "Baby Blue," from 'British rock band Badfinger, played over Walt's last minutes. The song is from the band's album Straight Up and was a Billboard top 20 hit in 1972.

Badfinger's "Baby Blue" follows a string of memorable blue-themed musical numbers for Bad, including "Crystal Blue Persuasion," by Tommy James and the Shondells, which was used in last year's mid-season finale.

"Baby Blue's" lyrics are appropriate for the end of Walt's journey, with lines such as "I guess I got what I deserved" and "I would show the special love I have for you, my baby blue."

That Walt spent his final moments in a lab that created his signature problem implies he had a fondness for his memories, even after all the horror it caused. The song added some levity to quite a sad moment, and we only wish Walt could have heard the music.
