* Definition av låtversion: Den version av låten som ni hör spelas.
Notera att originalversionen av låten kanske inte är tillgänglig i alla musiktjänster. Oavsett, så söker vi alltid året då artisten först släppte låten. In addition, sometimes songs have been remastered and the original song is no longer available. On such occasion, it is the original song release year with that artist that we are looking for, not the year it was remastered.
** Definition of year: The year the song was first digitally (download or stream) or physically (single or album) available to the public on any market.
