Since i'm working on my laptop running GNU/Linux, i was having the problem of not listing to music online, for example LAUNCHcast is compatible only with MS programs, there are some tries to make them work with Wine or CrossOffice, but i'll definatly not use IE on GNU/Linux, it's more like "Shooting yourself in the Foot", however i searched the net to find a solution for LAUNCHcast, nothing good, so i ran a search for "online radio", the very first result is Live365.com, i browsed my favorite genre, a popup window opened, then i was listening to music. It was plug-in of xine for firefox i guess, the frontend of xine is gxine, xine is a GNU/Linux multimedia player.
There's one thing i need yet, control xine with KDE applet "Media Control"
