Classic rock and most styles of Japanese music. From time to time I also love indulging myself in classical, jazz, blues, swing, funk and other forms of truly inspirational instrumental genres.
Edit: Didn't realize we were also posting genres we dislike. There are exceptions to this rule, but I hate anything that sounds repetitive and uninspired. I can respect some forms of rap but most of it sounds noisy and the lyrics sound distasteful. I also dislike country because most of it is the same thing. Hip-hop is just generally painful to my ears, along with heavy metal and screamo. Punk music for some reason makes me feel uneasy and anything with auto-tune is an absolute nightmare. That haunting sound of a human's voice taken over by a machine is simply unbearable.
An example of an exception to the rule- Eagles definitely have strong elements of country in their music, but it's just so inspired that I love it. "Take it Easy" is a great example.
