Adding Multiple tracks to playlist at once

I'm facing a more or less big problem right now. I want to add multiple tracks to a playlist. I could do it by hand but it takes quite some time to add hundreds of tracks. Some kind of multiselect would be appreciated. For adding and deleting. Does anyone have an idea how to do it / which api to use?

I don't think there is a multi-select of any kind, unfortunately. You might want to look into Roll20 Audio Master, available in the one click install. I believe it will not only honor your playlists, but allow you to create your own. You may find the interface more friendly. I'm not sure, I don't mess around with the jukebox nearly as much as I used to. Roll20 AM basically creates its own "virtual" track list and play lists, using the built in ones as a guide, which can be a stumbling block for new users. Just remember that any time you make changes to the Roll20 Jukebox, for those changes to be recognized by Roll20AM, you must delete and import all tracks from it's database.Not nearly as scary as it sounds. It's literally pushing two buttons and finishes nearly instantly.

Can the playlists created by AM be used via Jukebox? 

No, Roll20AM does not affect the actual Jukebox in any way.

Damnit, cause I really want to use the actual Jukebox. Thanks nevertheless: D
