A week after launching its paid streaming music service, Amazon announced a deal with one of streaming music's biggest holdouts: country superstar Garth Brooks.

Brooks, the best-selling solo artist in U.S. history with 138 million albums sold, has kept his music off streaming services. On Wednesday, select albums and songs will be available on Amazon Music Unlimited.

His albums, previously available only through his GhostTunes service, will be sold digitally via Amazon Music.

Brooks said he waited until the right partner came along before he was ready to dive into streaming.

"I love retail to death, but retail will never tell me what my stuff is worth and will never tell me how to sell it," Brooks said in a telephone interview from Los Angeles. "That's the tail wagging the dog for me."

"This is a landmark moment for both Amazon Music and Garth Brooks," said Steve Boom, vice president of Amazon Music, in a statement. "Garth Brooks is a legendary country music superstar who continues to shatter industry records and amaze fans three decades into his career. We are honored to make his music available for streaming for the first time ever, exclusively on Amazon Music."

Brooks entered semi-retirement in 2000 near the height of his popularity to spend more time with his children and wife, Trisha Yearwood. In 2014, he returned with a major tour and a new album, "Man Against Machine."
