Have Music from @Music Command Not Reset When Changing Maps

Anyone who has ever used the music command will know that the utility of the command is restricted to activities confined to the same map/channel for long periods of time, e.g. grinding, farming and leeching. This is because whenever the player changes maps or channels, the music will default back to the original music associated with that map. This means that one can't even use it in long boss fights such as HT and PB (prehead and banish maps) without being greatly inconvenienced by the need to repeatedly use the command and search for the desired song.

If at all possible, I would like to suggest that the song selected by the player using the @music command persists even through map and channel changes. However, because this may prove awkward for when the player might actually like for the music to be reverted to the default, I would also propose that there be an option for this under the @music command or for there to be a separate command such as @stopmusic.

Stretch goals:

• Allow players to search for songs instead of having to scroll through everything, or at least have the song list be sorted in alphabetical order
• Allow players to build a playlist (currently there is only a shuffle option that goes through every song in the catalogue)
• Add more songs to catalogue
