The follow up, ''Ne moga'', rapidly exceeded the success of its predecessor and brought the singer the award for best female performer of the BG Radio. A song, named ''That one'', wrote and arranged by Magga for the teenage idol Rushi Vidinliev, first single from his third homonymous album, marked a significant progress in the young mans career and topped all the local charts in 2006.

They called it ''Trinity Studio''. The first cut was Beloslava's latest album ''Listen to me''.
