WHY 5SOS?

Some weeks ago, our English teacher Violeta, prupoused to us to do an oral presentation about a group or a band. At first, I wanted to do it about a Catalan music group, but then she said that it had to be an English singer or band, so I chose 5SOS because I didn't know a lot f things about them.
I have a friend that is a big fn of 5 seconds of summer. She is Salma, she has all the CD's, she knows all the songs...
When I was on ecundary school Salma put a song of them, and it rangs a bell to me because it wasn't the first time that I heard it That song was called "She looks so perfect" and it's one of their famous song. Then I asked her which was the name of that group and she told me that was 5SOS. When I arrived home I searched on youtube songs of 5SOS ans I like it so I downloaded a lot of them!
Next day, at school, I told Salma that I liked that group, so when they published a new song, Salma always tells me, and then I search it and listen to it.
In short, I chose this group because I didn't know a lot of them, I only listen their music but I didn't know their biographies and all that jazz.
