Your view is common in the modern world, but it is not the historic Catholic teaching of St Thomas Aquinas and other philosophers and theologians in Catholic Tradition.
The historic Catholic philosophical teaching is that
everything that exists, including art and music insofar as it exists is true, good and beautiful. These number among what in traditional Catholic philosophy is called the
transcendentals. There is some debate as to whether beauty is its own proper transcendental or whether it is simply the combination of the good and the true, but in traditional Catholic philosophy there is no doubt that beauty – in all its forms whether moral, artistic, musical or physical – is objective in nature, inhering in the object which the mind recognizes beautiful.
This can be proved philosophically from the fact that when the mind apprehends something as beautiful, there must be a quality of the object by which the mind apprehends it as beautiful.
This historic, traditional Catholic position comes as a surprise to many because secular society educates them to believe otherwise. For example in many schools they will teach children what is supposed as a difference between “fact” and “opinion.” In some of the examples they will say that the statement that a certain art work is beautiful is not a “fact” (or a statement in contradiction to a fact) but is rather an “opinion.” This and other forms of societal brainwashing causes people to lose sight of the objective character of beauty. This aesthetic relativism is a dangerous counterpart to moral relativism and as such part of the “dictatorship of relativism” condemned by Benedict XVI prior to the conclave.
Pope Benedict XVI also condemned while Cardinal the lack of objective beauty in certain music:
“On the one hand, there is pop music, which is certainly no longer supported by the people in the ancient sense (
populus). It is aimed at the phenomenon of the masses, is industrially produced, and ultimately has to be described as a cult of the banal. “Rock”, on the other hand, is the expression of elemental passions, and at rock festivals it assumes a cultic character, a form of worship, in fact, in opposition to Christian worship. People are, so to speak, released from themselves by the emotional shock of rhythm, noise, and special lighting effects. However, in the ecstasy of having all their defenses torn down, the participants sink, as it were, beneath the elemental force of the universe. The music of the Holy Spirit’s sober inebriation seems to have little chance when self has become a prison, the mind is a shackle, and breaking out from both appears as a true promise of redemption that can be tasted at least for a few moments.”

What you are observing here is completely compatible with the objective nature of beauty. Beauty’s being objective does not mean that there cannot be manifold, diverse expressions of beauty, different kinds of participation in Beauty.
It is not simply academic but critical to our relationship with God that we recognize that what He made – including things as simple as trees – were made by Him objectively beautiful, reflecting in however a dim way His Beauty. In music and art, insofar as we accurately reflect the eternal Beauty of God whether in sacred or profane* music, they too are objectively beautiful.
