Interesting topic. I tend to gravitate more toward “progressive” styles, be they rock, jazz, contemporary… I like unpredictable music that catches me off guard. I tend to dislike traditional “chamber” music for this reason, and most pieces by Mozart. Granted the guy was talented, but I find his stuff rather boring. What really excites me musically are composers like Alan Sylvestri (soundtrack from the movie The Abyss) and rock/metal bands like Rush and Dream Theater. I do like Celtic music on occasion but can only take it in small doses. If I can predict the rest of the song after hearing the first 3 chords, I tune it out.
