they worked on the album until the fall of 2001. paul and paula succeeded to mostly finalise the album and they decided to include cezar stănciulescu and cristi ştefănescu, members of the band nsk. the two were excellent professionals to work with. it was the first album in which all the lyrics were written exclusively by paula. the title of the album was "știi ce înseamnă (să fii fericit)" (you know what it means (to be happy)), and includes songs like "promise"/"promit", one of paula's most famous songs, that was available in romanian, and in english, as well. also in 2001, a truly intense year, paula released the album " prima selecție " (first selection), a song collection from concerts, duets and remakes of some of her best songs. in the same period, the teen star, worked with an artist that she found very interesting: puya from la familia. they arrived early at the studio where she was recording a song with a strong message and puya had not found a female vocalist yet. the song seemed very suitable to paula's abilities and she offered to record it with him.
