I know I am a broken record, but I can't stress enough how much a great pair of headphones have changed my music listening. My old ones broke, and I stepped up to the Sony 1000Xs because I stumbled on a great deal for them. It makes me hear things in songs I hadn't heard before, even if it's the 100th+ time I've heard it. It's also made me like hip hop and electronic music a bit more too.
A recent example was I think
@krista4 's Dobie Gray pick yesterday. I ended up listening to it at least a half a dozen times in a row. Awesome.
They do not, however, make country music any more tolerable.
