This is Basshunter.
His real name is Jonas Erik Altberg and
was born 22 December 1984 in Sweden.
He's is a musician Wiki
The first song I heard from Basshunter was Now You're Gone
and it was number 1 hit in 2009 and I liked that song because it had very cool music.
Later on that year I heard his newer song All I Ever Wanted and I like that song
just as much. Also reached number 1 hit as well.
At the end of that year I started using a music program FL Studio and it
is what I use to make music. Then in 2012 I found out that Basshunter
uses FL Studio as well.
