I’m not sure how I would clear an alias, I tried a few things but I couldn’t figure it out.
However, I have a solution for you:
Edit your !song command:
!editcom !song Display current song
Create a _lastfm command:
!addcom _lastfm @$(touser) Current song: $(lastfm Andybrew3 "{{title}} by {{artist}}")
Then when you edit !song, replace the alias with either _lastfm or !songs current according to what you want.
So if you want to get the songs playing from Spotify, use:
!editcom !song -a=_lastfm
And if you want to get the songs playing from the AutoDJ, use:
!editcom !song -a=!songs current
To make it even easier on your mods, you could create a command to switch the source so they don’t have to type or copy/paste everything every time they have to switch, it would look like this:
