One reason I postponed entering the Church was because of my ambivalence towards the music and liturgy found in typical Catholic parishes. I actually did not know what the true teachings of the Church on sacred music were, according to the documents of Vatican II, until 1991. Also, I did not know that there were any Catholic parishes where good music was still done. All that changed when I read the documents, and when in 1991 I started attending the Sacred Music Colloquium, held by the Church Music Association of America (CMAA).
