Bruno Mars has been releasing music since 2009 and he continues to today. Many of his songs are very popular and is difficult to make songs that have changed. Most of the time when an artist is known for making a certain type of song he usually doesn’t change the way he writes the songs because his fans are used to what he writes.
However Bruno’s music has evolved over time from when he first hit the mainstream until now. His first album was considered to be in the music genre of pop. Over the years his songs have been rock, reggae, R.&B, soul and hip hop. So his music has changed into different genres. It’s amazing that he has this flexibility.
