5SOS or 5 Seconds Of Summer, is one of the best bands in the universe (in my opinion),the other best is Hey Violet. I was amazed when they introduced these emojis, and because of it, the only information i can find (unless you know a website) is what I have here. From what i can see, I think the one with the bandana is Ashton, the one with the black hair is Calum,the one with the lip ring is Luke, and the one with the red hair is Michael !!!
In case you don't know who they are, here is a video of them singing one of their hits 'Don't Stop' (no emojis)!!!!!
These are my 3 favourite 5SOS Songs ; '18','English Love Affair' and 'Rejects'
In the paragraph about 5SOS, I mentioned another band 'Hey Violet'. They unfortunately don't have an emoji (I don't know why!!!) but they are awesome and I want you to know that. Here is a video of one of their hits 'Sparks Fly'
Along with 'Sparks Fly', here are my other 2 favourite Hey Violet songs; 'You don't love me like you should' and 'This is why'
