Post Malone just released his country album F-1 Trillion. Earlier the year, the hitmaker covered Dwight Yoakam at Stagecoach, then in July he joined the country singer-songwriter onstage in LA. Now, Posty and Yoakam are sharing their collaboration, which is Yoakam’s first new song in nine years. According to a press release, “the song was written specifically by Yoakam for a collaboration with Post Malone.”

“I Don’t Know How To Say Goodbye (Bang Bang Boom Boom)” is from Yoakam’s forthcoming album Brighter Days. Last month, F-1 Trillion debuted atop the Billboard 200, and Post Malone became the first artist in history to score #1s on the Top Country Albums, Top Rap Albums, and Top Rock & Alternative Albums charts. This week Billboard also named “I Had Some Help” as Song Of The Summer based on chart metrics.

Brighter Days is out 11/15 on Thirty Tigers.
