Are there any more refined words than psukim? What refined words do you ever find with secular music? If you take the most “pop” of our world, you have Yossi Green. He can be defined as a commercial composer, but he is an eved Hashem who really doesn’t need the money (he is a successful businessman). Boruch Levine is a very well respected mechanech, and so is Shmuel Brazil. The Chassidishe composers all compose for their rebbeim and it is only afterward that the tunes make it into the commercial Jewish music world. Ki Hierbeiso is a perfect example of that – it was so good that Avraham Fried and Lipa bought it from whoever wrote it for the Lelover (?) simchas beis hashoeva. Avinu Malkenu Psach Shaarei Shamayim was a Belz nigun that I think was also composed for an SBh”S and it spread into the popular Jewish sphere. Mendy Werdyger puts out albums of such new Chassidishe neginah every so once in a while as well.
And even Yossi Green’s music clearly fits the lyrics and has the right beat and feeling to enhance the message of the psukim that it accompanies.
The secular composers just turn out whatever the market will bear. Some of their messages – rebellion, drugs, free love – are completely against Torah.
