When Mutemath frontman Paul Meany sings, “I still light up for you,” on the band’s new song “Light Up,” it’s more than theoretical: he wrote the tune about his relationship with his wife. The track premieres today on Speakeasy.

The song bubbles along through the verse, accentuated by electronic handclaps and a synth-funk vamp, then expands into a bright, airy chorus with just a hint of influence from the early-’80s danceable pop sound that included Michael Jackson. Meany describes it as a “reality check” for the work that goes into turning the initial spark of attraction into a lasting love.

“The excitement of a start is always at risk to fade over time,” says the singer and keyboardist, who has been married for 17 years. “The acceptance of an end is painful, but when processed right is turned into the rebirth of another start, another spark.” “Light Up” comes from Mutemath’s upcoming album “Vitals,” the band’s fourth full-length album and the follow-up to the group’s 2011 release “Odd Soul.”

Meany and drummer Darren King started Mutemath in 2002, and the group eventually expanded into a foursome that now includes bassist Roy Mitchell Cárdenas and guitarist Todd Gummerman.

“Vitals” is due Nov. 13. What do you think of “Light Up?” Leave your thoughts in the comments.
