I used to be shallow with my music. But I am not that immature high school kid anymore.
I just listen to whatever I find myself enjoying now. Regardless of genre, singer, if it sounds like anything else. I view music now with no expectations. And I am finding it to be well worth not having any expectation for music, as I am enjoying a lot of music that most people are finding not to their liking, and usually people respond with "I did not expect" and their expectations were not met so they became disappointed and it affected how they enjoyed the song/album/band. I would usually listen to songs from throughout their catalog if I can, or from their most recent album, their debut, and their most famous album.
This stems from my perception of how music is vibration and sound and how it's everywhere, and if you put a melody, beat, or harmony to those sounds you can create music, which is the basis for Stomp. Also, I was playing with Ableton and messing with pitch correction and made it all high and the human women voice sounded like a bird, and then I thought, huh...I wonder if you were to pitch correct a birds noise, if it would be saying something in some language.
So my music listening is based entirely on my perception of music and how I view what Music is and how it is heard and used throughout the world. And I am noticing that people have many different perceptions and views on how they perceive music.
