Me too, but I think that it would still be an ideal move. Back in 2013, she said in an interview that the reason why she wasn't competing with her own material was because jazz was a niche genre for the contest. She was right to a certain extent, it's easier to sell Swedish imports, but people like Raphael Gualazzi, Rona Nishliu and Jamala were all involved in jazz music (and they all did really well). Salvador is serving us another kind of jazz tea and he apparently is bound to do quite well....
If all that isn't an incentive to show what sort of jazzwoman she is
This could help San Marino not to be blacklisted by juries and they could surprise with an entry whose quality people wouldn't expect from them. In 2014, they qualified with a ballad, so instead of going for straight pop with no results, a jazz ballad would definitely be something worth a try. They don't have many options to begin with, but I can't understand why they haven't considered that.
