Weezer's "Back to the Shack" makes a monstrous splash at both rock and alternative radio this week.

Weezer’s first single in three years–and first major label release in more than four–is off to a strong start at both rock and alternative radio.

According to Mediabase, the tune scored pickups from 20 monitored active rock stations and 25 monitored alternative stations to rank as the most-added song on both formats. No other song on either format received more than half as many adds.

Chevelle’s “Hunter Eats Hunter” (10 monitored adds), A Day to Remember’s “End of Me” (9) Last Internationale’s “Life, Liberty and the Pursuit of Indian Blood” (9) and The Black Keys’ “Gotta Get Away” (7) made the next four biggest splashes at active rock.

Other top additions at alternative included Alt-J’s “Left Hand Free” (11 monitored adds), Priory’s “Weekend” (8), Bastille’s “Flaws” (7) and Griswolds’ “Beware the Dog” (6).

The lead single from the band’s upcoming album “Everything Will Be Alright in the End,” “Back to the Shack” is already #42 on Mediabase’s rolling alternative airplay chart.
