This is my opinion. There is a few that I consider to be good, but the majority of American music that hear that are considered popular on the radio are just plain stupid if you pay attention to the lyrics. The lyrics either:
1) Makes no sense at all and the only reason the music is popular is because it is a dance song
2) They talk about how they get b*tches and what a baller they are
3) They talk about some kind of drama in their life (the problems are often so minor and stupid that it shouldn't even be worth mentioning)
When I listen to Asian music, it is completely different and are generally more positive or soothing. The type of music I really enjoy right now are Chinese music from Tawain. Chinese music is pure art. The lyrics are just pure poetry and requires a creative mind to actually understand the meaning, unlike American music, which is really dumbed down. One of the artist that I really admire is Jay Chou. He uses anicent chinese musical instruments and put a modern twist to his music, which I find very creative. I can't believe I did not listen to him more when I was in college, when he was really popular then.
American music is very rich in diversity so the while "getting the b*tches" is a popular theme in rap music, it doesn't represent Amrican music. Rap music sells both in the US and abroad so many foreigners are into vulgarity as well. Kinda of disturbing. Pop culture also has lots of songs that are written about people's personal things and not from poetry, I agree. However, it is the common personal experiences that also create an emotional experience.
It seems you like the technical aspect of music, the complexity of poetry writing and musical creativity. When defining "creativity" again, your notion may not agree with other people. As you say using an instrument in a non-tradtional way, this is employed in both American and Asian music, as a harp, flute, or piano in rock music for instance.
How long have you been in the US? The longer you're here, the more aculturated you are and the more exposure you have to the diversity of the music.
