interesting post gizmo. i never thought of playing webstreams with normal audio player because i changed from centrafuse and there is no way to play streams with stock audio player... but my personal advantage of this plugin is, that i have an own webradio button on homescreen. another one is, that the trackname doesn't show up correctly when starting some *.pls or *.m3u stream in audio player (like from di.fm). somehow it works with webradio plugin!
edit: had managed it to show trackname of streams global. now i'm 100% satisfied!
