To be honest, no priest I've ever worked with has trusted my opinion when it comes to music,
Why does your priest not trust your opinion on this? That's a huge red flag.
"I'm going to call someone who knows about music."
In the next place, that irreverence may be avoided...They shall also banish from churches all those kinds of music, in which, whether by the organ, or in the singing, there is mixed up any thing lascivious or impure; as also all secular actions; vain and therefore profane conversations, all walking about, noise, and clamour, that so the house of God may be seen to be, and may be called, truly a house of prayer.
Q: What are the characteristics of sacred music?
A: On the centenary of its promulgation, John Paul II urged us to revisit and learn from St. Pius X’s letter motu proprio on Sacred Music, Tra le sollecitudini (1903). Pope Pius distinguished three characteristics of sacred music: “it must possess holiness and beauty of form: from these two qualities a third will spontaneously arise — universality” (§2).
Concerning holiness, for music to be sacred means it is not the ordinary, not the every-day. It is set aside for the purpose of glorifying God and edifying and sanctifying the faithful. It must therefore exclude all that is not suitable for the temple — all that is ordinary, every-day or profane, not only in itself, but also in the manner in which it is performed. The sacred words of the Liturgy call for a sonic vesture that is equally sacred. Sacredness, then, is more than individual piety; it is an objective reality.
Concerning beauty, the Latin speaks more precisely of bonitate formarum or “excellence of forms.” This refers to the tendency of sacred music to synthesize diverse ritual elements into a unity, to draw together a succession of liturgical actions into a coherent whole, and to serve a range of sacred expressions. Excellence of forms also serves to differentiate those elements, to distinguish the various functions of liturgical chants by revealing their unique character. Each chant of the various Gregorian genres presents a masterly adaptation of the text to its specific liturgical purpose. No wonder the Church has consistently proposed chant as the paradigm of sacred music.
Sacred music must be true art, says Pope Pius, “otherwise it will be impossible for it to exercise on the minds of those who listen to it that efficacy which the Church aims at obtaining in admitting into her liturgy the art of musical sounds.” Beauty is what holds truth and goodness to their task. To paraphrase Hans Urs von Balthasar, without beauty, the truth does not persuade, goodness does not compel (The Glory of the Lord: A Theological Aesthetics, I: 19). Beauty, as expressed in the Church’s liturgy, synthesizes diverse elements into a unified whole: truth, goodness, and the human impulse to worship.
Concerning universality, sacred music is supra-national, equally accessible to people of diverse cultures. The Church does admit local indigenous forms into her worship, but these must be subordinated to the general characteristics of the received tradition. By insisting on the continuous use of her musical treasures, especially chant, the Church ensures her members grow up hearing this sacred musical language and receive it naturally as a part of the liturgy.
The children in costume will process before the ministers.

Oh well, undoubtedly the 4th graders (or some class of kids) will be in their saint costumes. My kids have all done that - - not so bad is it? They wear their saint costumes all day, so of course they will wear them to Mass.
How exactly is singing "I wanna be a saint" impure or unholy?
