Album Pentatonix (Pentatonix). Songs and videos online

"Pentatonix" is the eponymous fourth studio album by American a cappella group Pentatonix, which was released on October 16, 2015 on the RCA label. The release date was announced on Twitter by a series of pictures featuring the five band members released over a five day-span, with one band member added to the picture each day, culminating in the date being revealed on August 28.
This is the first release of the band to feature predominantly original material (the only covers being the cover of Shai's "If I Ever Fall In Love" and the four bonus tracks in the deluxe versions of the album). Pentatonix also marks the first time band members receive individual songwriting credits for the majority of the tracks.
