By 1939, many things were changing. The first movie to be filmed in color was during this year, diesel locomotives were being invented for trains, and the World's Fair in Manehattan got a lot of ponies to go see what may occur in the future.

Music also changed during the 30's, and 40's. New musicians were arriving, and a new type of music was formed.

With an electric guitar, a piano, and sometimes a drum, Rhythm, and Blues was the new form of music created by some ponies down in the south. Most of them were African Equestrian, and this type of music would soon lead to another new form of music.

Sixty years ago in 1954, Rock & Roll was invented. The first Rock & Roll song created was called Rock Around The Clock, by a band called Bill Haley & The Comets. Soon, hundreds of ponies started playing Rock & Roll.

Lyra: The best music ever invented. Bill Haley was a genius when he created Rock & Roll.
Bonbon: The 50's were about good times. Getting a fancy car, going to diners to have burgers, and milkshakes, and listening to Rock & Roll. That's what all the teenagers would listen to.

Although Rock & Roll was very popular with teenage ponies in the 50's, adults were not too happy with it. They thought it was vulgar, bad, and the worst thing you could listen to.

However, there were still some ponies that played Jazz music. Such as Dean Martin, Flank Sinatra, and many more.

Vinyl Scratch: I don't know what their deal was, with those ponies getting angry with their kids for listening to music that they enjoyed listening to. It doesn't seem right.
Fluttershy: Oh, I like Rock & Roll. I like every kind of music.
Octavia: The Rock & Roll songs that were created sixty years ago, made many adult ponies angry. They didn't think it was good music, and they sometimes blamed it on their children, if they were getting out of line.

In the early 60's, word soon spread in the U.K about the new form of music, so a few British ponies started making their own Rock & Roll.

One of the popular British bands was The Beatles. Ponies all over the world heard their songs, and fell in love with them.

Twilight: Man, the Beatles have a lotta swag. They must've gotten inspiration from some of dem rappaz to make music, you know what I'm sayin?
Pinkie Pie: A band named after a car I have! Wunderbar! I love german music!
Interviewer: Pinkie, The Beatles are British.
Pinkie Pie: That's what you think, but they won't fool me.

As a result of what was happening, Rock & Roll became the new type of music that everypony wanted to listen to.
