We shall discuss an approach to define typical irrational rotation numbers for circle maps with singularities. It is based on considering one-parameter families of such maps. This approach allows to define new probability distributions on rotation numbers which are universal, and depend only on the local structure of singular points. We shall also discuss an application to Kesten-type results on statistics of hitting times.
