'Firefly' popularity quickly spread due to a lot of reasons. The music video was visually great, and everyone could see that a lot of money had gone into it. The song itself was a great one, and everyone was mesmerised by it.
Aiden's fans had not thought that one day he was going to collaborate with Rachel, the person who had eliminated him on X-Star.
But it was a pleasant surprise.
A lot of people were astonished by Rachel's high vocals, which hadn't been used properly in her previous songs and were in awe of it. Her dance moves were praised a lot too.
As for Aiden, his style of composing suited 'Firefly' a lot and everyone could see that he had exceeded himself this time.
The high vocals, great lyrics and the way of singing — Everything was top-notch.
