Is it too late to report a song from 2017?

SAMI has a ten-year statute of limitations for songs played in Sweden, so you can definitely submit recording lists for ”old” songs.

Collecting societies in other countries, however, have their own rules and the limitation period is often between three and five years. This means that you can get the Swedish remuneration for an ”old” song if it has been played, but that the opportunity to claim your remuneration from other countries may be lost.
