Ubuntu’s B-Sides: Alternative Apps

“Those not familiar with the term B-side have to go back to the
vinyl recording days. Singles were 45 RPM records that on their
A-sides usually had a cut from a band’s newly released album.
Because singles had two sides, the B-sides often had a less known
track that didn’t appear on the album. Although the B-sides didn’t
(with some exceptions) achieve the popularity of the tracks on the
A-sides, they were more or less bonus material and highly sought
after by collectors.”
