Domestic interest increased in Soulwave, which released its first Hungarian-language song, "Szélcsend", which also debuted on Petőfi Radio and topped at 27th place on national music charts, which had a decisive influence on the band's decision to further record Hungarian songs. Soulwave signed a recording contract with Universal Music Group, the main music publisher of Hungary. Their first single under Universal was "Mindent Elhittem" which was a hit.
