The differentiation of the individual streams of Slovak catholic liturgical music became obvious in late 1980s and the process continued during the 1990s. Opinions in this period varied a lot. Such affinity results in latent but sometimes even manifesting conflicts. Rhythmical songs of youth choirs became a real alternative to the Unified Catholic Songbook. In the beginning the older generation thought the repertory to be a profanation of liturgy. Yet, in the second half of 1990s, even the older churchgoers gradually started to accept the new music of the youth. This caused a change in the social impact of this genre. As indirect consequence further development was greatly slowed down.
