According to Hollywood Life, Justin has been showing his sensitive side to Selena by writing love songs for her. "Yes, 'Life is Worth Living Again' was all for Selena and that is not the only song he has written for her. He has written a bunch of other stuff for her, she is his biggest inspiration, a source said. Media and fans speculate that Bieber's newfound happiness is because of Selena reuniting with him.

However, the song has an optimistic feel as the chorus reads, "Life is worth living, life is worth living. So live another day." The song's positive vibe is a breath of fresh air for Bieber whose previous single was entitled "Broken." It was released in February when the pop star successively took aim at media and his haters.

Justin and Selena fans are hopeful that the 20-year-old pop star would take the song on tour with Selena. The power couple are reportedly planning for a joint project which couple possibly be the answer to every Jelena fan's dream. "Ticket sales would be through the roof and they desperately need the positive publicity after Justin's bad boy behavior and Selena's stint in rehab," an insider told Star magazine.
