Led Zeppelin’s “Immigrant Song” got quite a boost after being used in the trailer for Thor: Ragnarok.

Over 7,000 downloads of the track from Led Zeppelin III were sold in the week after the trailer debuted. That was enough to land it at number-16 on Billboard’s Hot Rock Songs chart. It’s the first time the long-defunct band has ever appeared on this chart, since it was only created in 2009 to tracks downloads, airplay, streaming and YouTube views.

Billboard says that older songs are eligible to chart if they end up in the Top 25 and “are sparked by new momentum in multiple metrics.”

“Immigrant Song” is one of the six Top 40 hits Led Zep had in its heyday, peaking at number-16 in early 1971.
