The songs I send to the contest is a mix of what I personally like and what I think at least some people will enjoy. I try to imagine that "this might be a song that could be liked by at least person A and B", and sometimes I am right and sometimes completly wrong. The great with that is you can be so surprised with some songs you send, that can be loved with people you would never think of.
I also like to send pretty wide range of songs which means that if I go rock one time, I may go for a ballad next and the one after that go for a pop song. But all songs are what I personally like, and I would like people to see and find, cause after all, the thing I like the best with this contest is to find songs I would never personally have listened at and just fell in love with them. And I know how bad it feels when you never qualify, back in NSC 20s and early 30s, I qualified only twice in 12 editions....and never got better than 23rd. So yeah, there are times it is rough being in the contest, but eventually, when you least expect it, you sit there infront of the computer and are fighting for the victory with a song that you in your wildest dreams never thought would do that well. That is a part of the beauty of the contest.
