Brothers Osborne are feeling grateful for their first No. 1 single, "Stay a Little Longer," which siblings TJ and John Osborne wrote with Shane McAnally. TJ and John shared their appreciation with the country radio community in a heartfelt note, with the reveal that their next single will be "21 Summer."

"What a journey it's been!" they write. "The love and support you all have shown will never be taken for granted. You have truly made a dream come true for us. We look forward to our future together."

TJ admits that it's hard for him to describe the feeling of having their song hit the top of the chart. “It’s crazy. Honestly, it’s beyond surreal,” he says. “It’s hard for me to describe it really. I just feel really just more grateful than anything.”

His brother agrees, adding that the duo spend so much time writing and performing that they often lose perspective that any progress is being made.

"For this to happen for us, especially at this point in our careers, is one of the highest honors that we could ever ask for, and it’s definitely something that we’ll never forget for the rest of our lives,” John concludes.

"Stay a Little Longer" is nominated for Best Country Duo/Group Performance at the 2016 Grammy Awards. It is featured on their debut album, Pawn Shop, which was released in January. Brothers Osborne will join Miranda Lambert and Kip Moore on the Keeper of the Flame Tour in 2016.
