Train Song Debut: "Hey Soul Sister"

Known for early-millenium hits like "Drops of Jupiter (Tell Me)" and "Meet Virginia," Train is back and gearing up for the release of its fifth studio album, "Save Me San Francisco," due October 27 on Columbia. Exclusively on Billboard.com, listen to the band's new single, "Hey Soul Sister," a plucky song about a woman who's got all the right moves.

Like the rest of Train's new material, "Hey Soul Sister" marks a return to the group's folk-rock roots. "There's super catchy riffs and melodies in it, which I think are way more important that any production trick or great-sounding vocal production," says lead singer Pat Monahan. "It's kind of us going backward so we can go forward."

The frontman, guitarist Jimmy Stafford and drummer Scott Underwood took a three-year hiatus after their 2006 album, "For Me, It's You," and reunited in April to record "Save Me San Francisco" in London. Producer Martin Terfe (Jason Mraz, KT Tunstall) helped craft the sound of the album, which pays tribute to Train's hometown. "We owe all of our gratitude to San Francisco because they embraced us back when, if they hadn't have, no one would have," says Monahan.

Now Train is hoping that all of its supporters will embrace the new material. "I think Train fans who have watched the good and the bad," says Monahan, "are really going to like this record a lot - I think, much more than they have in years."
