Listen to Journey on iHeartRadio

Journey's Arnel Pineda admits he's "still in disbelief" over the dramatic turn his life has taken.  The singer tells Rolling Stone that joining the long-running, internationally famous rock band led to his world "being turned upside down -- but in a good way, a fantastic way." 

He adds that while the past six years haven't always been easy, becoming Journey's lead singer has been "such a blessing." 

Fans can learn more about Pineda's experiences transitioning from singing in clubs in the Philippines to fronting Journey in the documentary Don't Stop Believin': Everyman's Journey.  The film, which chronicles Arnel's first year with the group, is hitting the small screen Monday night.  It's making its TV debut as part of PBS' "Independent Lens" series.
