Bieber, 22, and West had hit the studio together in 2015 creating tracks with a "New York vibe" but none of the songs made their way onto his album "Purpose" or rapper's LP "The Life of Pablo " but the singer is hopeful they will be heard in the future, reported Femalefirst.
"I don't know ... Maybe ... Hope so," he said when asked whether the tracks will make it out of the vaults.
The "Sorry" hitmaker, has worked with West on his "Never Say Never" - The Remixes album.
