I think that pretty much states what I want from a music player; what I definitely do not want is a music player that will, by default, start fetching metadata about my music from Internet sources... or, even worse, changing the metadata I've applied to my music using that Internet-fetched stuff as its replacement! (Internet metadata for classical music is always, and without exception, 100% utter rubbish, so you never want to see it being fetched or applied to any music collection you care about). On the other hand, whilst I don't want my music player pulling information down from the Internet, I would like it to be able to push it up to the Internet: specifically, I use Last.fm to record my music listening habits. Being able to 'scrobble' to that service is important to me (being able to scrobble to the similar, but open-source, Libre.fm is a nice-to-have feature, too).
