MPD is pretty popular too http://www.musicpd.org/
It has a client/server model and you can create your own music streaming service by controlling it remotely and streaming back over http.
ncmpc/ncmpcpp is a client for mpd that resembles cmus quite a lot.
I use cmus too. For those who don't know it is a command line music player with a VIM-like command line interface ("/" to search, ":set x=x" to set various options).
I agree. It's still more beautiful in my opinion though.
I don't like Chrome either, but a few parts of it are nice.
The thing I dislike most about recent Firefox releases is that the selected search engine influences URL bar search, which is rather annoying in my opinion, but then I removed the search feature from the URL bar, making them at least somewhat distinct again.
But there is a reason why Chrome looks like Chrome. Ironically, it's the lack of Chrome - the UI is unobtrusive and gets out of the way. I see the new Firefox UI in the same way.
I don't understand how curved tabs are supposed to get "out of the way". The new design seems to use less standard UI elements to push it's own (WinXP / Fisher-Price) agenda: I don't see any gains here and I reckon they just want to appeal to the chrome crowd.
I'm surprised Emacs was not mentioned. It provides a nice cross-platform interface to ... everything. Also everything (including looks) can be customized!
As someone who practically lives in Emacs running in Cygwin, I can second this, with some caveats: there are tradeoffs. Windows FS access and process forking are still dog-slow, even in native apps. To add to that, there are things I can't run in the native version of Emacs (w3m-el comes to mind), but you trade occasional lockups in Cygwin Emacs. Compare Linux where I run the same setup for Emacs for months if not years with no problems; even if Cygwin Emacs stays up that long, I will eventually (usually every week or so) be forcibly rebooted for Windows updates. If I never have to work with proprietary software again (especially Microsoft products), it will be too soon.
