As its been said, the line in method is great and all, but it screws up the aspect of shoutcast that is most appealing to indie artists like myself: broadcasting of band name and track title.
I do this for
www.radioaid.com. Radioaid is the brainchild of a good friend of mine... The main concept being to get good indie artists the airtime they deserve. So I play a mix of signed/unsigned. The "signed" bands get play as a means to rope in the people who normally wouldn't listen to indie radio... Having the names broadcasted means exposure for the indie artists, which is the intent of my radio show.
The line in method is a good idea for when I do live band sets, but at that point, I might as well use winamp once again... At least in winamp, shoutcast will be broadcasting something like "dexter methorphan live radio" so listeners will know what they are hearing.
The other beautiful thing, as I have said about MC, is getting that crossfader into action with shoutcast...
And as someone said about making m3u playlists and then just using winamp, of course... I do that for the first few tracks of the show to get going, then add things as the mood unfolds(in winamp) I'd love to be doing it all from my huge 6000song library in MC though, rather than browsing files in explorer and right clicking "enqueue in winamp" cuz I have made the mistake of accidentally selecting "play in winamp" which SUCKS. embarrassing...
anyway... SHOUTCAST!!!!
