My Hobby
Music plays an important role in our lives. I love to listen to pop music.
I love this type of music because it helps me relax. Besides,
Pop music started in the USA in the 1950s, then it became famous all over the world.
Some of the most successful musicians are pop singers Michael Jackson, Mariah Carey, Ed Sheeran, Justin Bieber and the list goes on.
I also watch music videos between studying sessions when I take breaks. My favorite pop song is James Arthur's "Impossible"; It's a beautiful song about hope and it makes me think about working harder.
