As for his album release, Shawn is looking forward to having fans across the country hear his new songs. And yes, he'll be hitting the road soon allowing music lovers to hear the tracks live.
"You have to think all of the time, effort you've put into making it. Be like, okay. Now it is going to come out. Let's go really, really hard for three weeks. Travel the world and show people the album," Shawn explained. "Because that's really what you want and it's fun. I'm going through a fun period now."
