Frank Sinatra is credited with having recorded a number of songs which can vary, according to different sources, from 1.100 to 2.200. The confusion is probably due to multiple recordings of the same song as well as to songs recorded for radio and television broadcasts but never published in singles or albums. The right number is probably just in the middle of the quoted ones. According to a very well documented list, anyway, he surely recorded not less than 1.133 different titles.
