Rascal Flatts will release its new single, "Here Comes Goodbye," to radio on Tuesday (Jan. 20). It's the first single from the trio's new Lyric Street album, Unstoppable, scheduled for an April 7 release. Rascal Flatts released a greatest hits album in October, but this will be their first collection of all-new recordings since 2007's multi-platinum Still Feels Good. Rascal Flatts co-produced Unstoppable with Dann Huff. "Here Comes Goodbye" was written by Clint Lagerberg and Chris Sligh.
