This Is Pop

E1. Auto-Tune

Love it or hate it, Auto-Tune has changed pop music. From Cher's "Believe" to Kanye West's "Love Lockdown," the sound has penetrated the globe and revolutionized music since its invention in 1997. Some say the pitch-correction technology has ruined music, while others have found fame by using the tool creatively. Tracing Auto-Tune's roots to predecessors like the synthesizer, the good, the bad, and the ugly of this game-changing technology is revealed, grounded in a personal account of Auto-Tune's most famous user, T-Pain.

E2. Hail Britpop!

Britpop. The word can elicit an eye roll, an itch to get on the dance floor, or a sudden urge to cry and sing "Wonderwall." In the early ‘90s, when America was hooked on grunge, The Brits retaliated with a return to catchy, witty, and downright fun pop, speaking to their own stories and cultural roots. This musical zeitgeist known as "Britpop" went far behind the headlines of "Oasis vs. Blur" – bands like Elastica, Echobelly, Pulp, Lush, and Suede became international exports with a unique sound.

E3. Stockholm Syndrome

Since 1974, when a little-known group named ABBA won Eurovision's song contest with their track "Waterloo," Sweden has been a global force in exporting pop music. Cassette players and bedroom walls have been filled with the likes of Roxette, Ace of Base, and Robyn, and ‘90s playlists featuring Britney Spears, Backstreet Boys, and *NSYNC would be obsolete without the work of Swedes Denniz Pop and Max Martin.

E4. The Boyz II Men Effect

Before Backstreet Boys, *NSYNC, and 98 Degrees, there was a "boy band" from Philadelphia called Boyz II Men that ruled the charts. With their incredible vocal harmonies and preppy-cool style, Boyz II Men became the "soundtrack to our lives" with hits like "End of The Road", "I'll Make Love To You", "Motown Philly," and "One Sweet Day" – heard at weddings, proms, karaoke bars, and funerals alike. Going back to the band's humble beginnings in Philadelphia, this episode pays homage to the influential R&B group who set the template for ‘90s boy bands.

E5. When Country Goes Pop

It's a tale as old as time – a country song goes "pop" and country music fans protest. From Dolly Parton to Shania Twain to Lil Nas X, the scrutiny around what makes a song "country" has been a raging debate that shows no signs of slowing down.

E6. The Brill Building in 4 Songs

New York City's Brill Building and pop music go together like bread and butter, or in this case, like King n' Goffin, Leiber n' Stoller, or Barry n' Kim. In the 1950s and 60s, songwriters, record producers, and wannabe pop stars flocked to 1619 Broadway in New York with dreams of churning out the next big hit. Full of small rooms with upright pianos, The Brill Building was labelled a "song-factory", but its true spirit grew out of a community that collaborated and challenged each other to achieve greatness.
