3. "Boyfriend Material"
The modern doo-wop banger "Boyfriend Material" was originally intended for Grande's debut album but didn't end up making the cut. As a thank you to her fans a year after releasing Yours Truly, the pop star ended up posting the track online for all to hear. The song received a second life when bought by K-pop group f(x) who kept the sound but changed its name (to "No More") and shifted its subject matter from a song about finding the perfect beau to a requiem for a boy-obsessed best friend, according to Billboard.
