'Priority') is the debut solo album by Greek singer Helena Paparizou, released on 27 June 2004 by Sony Music Greece.

The original album was only a mild success, however, following Paparizou's victory in the Eurovision Song Contest the Euro Edition peaked at number one on the charts and was certified platinum by the IFPI.

Before her participation in the Eurovision Song Contest 2005, Paparizou re-released the album with the title "Protereotita: Euro-Edition" on 31 March 2005.

At the end of 2005 Paparizou re-released the album for the third and final time in Greece and Cyprus as Protereotita: Euro-Edition + Mambo!.

Protereotita -including both re-releases- become a huge commercial success for Paparizou, considering that the album was released only in Greece and Cyprus.

My Number One included most of the songs from Protereotita: Euro-Edition, and was released in many parts of Europe including Sweden, Turkey,[4] Switzerland, Hungary, Finland, Slovenia, Russia, Denmark, Poland, the Netherlands[5] and Spain.
