There are several ways to stream your music collection to an Android phone.
Personally, I run Icecast
on my LAN Server at home and then use the "A Online Radio
" android app to tune into my Icecast stream.
But there is also MPD as a server with MPDroid as the remote-control for MPD
that can also stream the music, and XBMC
as the server with the "XBMC Remote
" app that can remote-control the server as well as stream the music.
Undoubtedly there will be many more - open source and without license cost.
