Everyone knows Foobar is the new Winamp.
But what about DJs?
It would be easy to add a second Player to the Foobar GUI which could be run simultaneous.
In the first Use-Case each Player should write to another output, so you can use your mixing console crossfader.
In second Use-Case a crossfader should be available with auto-crossfade options etc.
What about adding this?
If this is too much, just add a second instance of the player with different queue but same playlists and library :-)
btw there should be shoutcast etc support.
dont know if its already done.. long time no use ;)
