I can honestly say that most of the music I like sounds SO much better on headphones. Sometimes I just make the assumption that everybody else is hearing what I hear on most things (for example, the new Primordial) but then if you're actually only listening to crappy PC speakers, or a little transistor radio tweeter, than I shall stop assuming.
Joking aside though: headphones vs no headphones = night vs day
