The new rendition of "When You Believe" follows previous recordings by Mariah Carey and Whitney Houston. Pentatonix once again delivered a powerful collection of holiday tunes while Morris' vocals make it complete.
"Being apart of this song with these freakishly talented people gave me all my throwback choir/music vibes I needed. Get in the holiday spirit and listen to @PTXofficial amazing album out now," Morris shared to Twitter.
