I noticed that I haven't written anything about the speakers or the general quality of audio regarding the Asus EeePC 1101HA, so I guess it's time to fix that. In short, the speakers are no better than with any other laptop you may have used. They are definitely not designed for listening to music. They do well enough when playing speech driven games such as Monkey Island which only has ambient background music, but otherwise you're better off just muting the device altogether.
That being said, I find that the netbook's audio jack's output quality is from an entirely different world. Plug it into a proper amplifier and speakers and I, for one, couldn't tell it from a more professional audio source. :) The same goes for proper headphones.
While we are talking about audio, here are a few links to Spotify songs that you may use to either torture or gentle your ears, depending on your speakers (and personal taste):
