This is great information. Let me ask one dumb question. Is there a good
way to dynamically merge the 30-minute playlists from the separate sources?
In other words, I've got
music = playlist(mode='random', "/mnt/musicMount/watch/BLUES/")
comedy = playlist(mode='random', "/mnt/musicMount/watch/COMEDY/")
liners =
playlist(mode='random',"/mnt/musicMount/music/imported/4/unknown/unknown/")
If I want one thing from "liners" and then one thing from "comedy" and then
28 minutes from "music," can I make that happen? i thought merge_tracks
would do that, but it's clearly not for that. Should I be reading up on PLS
files to do this operation in the PLS file instead of inside of the
Liquidsoap code?
Thanks!!
