Stevie Wonder

His love for Syreeta Wright endured even in heartbreak.

Legend saw an opportunity to break new ground with a compilation.

Album set new standards for R&B, new standards for tech and new standards for artistic independence.

This first single was actually one of the last things added to 'Songs in the Key of Life.'

Album also includes singer's late father, Edward Severson Jr.

Gospel-flavored track appears on John's upcoming collaborative LP 'The Lockdown Sessions.'

He didn't have to prove anything by this point, but he doubled down on his legend anyway.

A song he cowrote, the first original to be released as a single, turned his fortunes.

His legacy-securing streak of five milestone albums between 1972-76 didn't come out of nowhere.

Synth pioneer influenced music throughout the '70s and '80s.
