I’ve made a plugin to search the Roblox Licensed APM music library!
It’s essentially designed to look like studio’s toolbox plugin, but more tailored to music discovery.
It supports favourites so that you can add candidate tracks into favourites and review after a browsing session (by filtering to show favourites only). These are stored as a studio setting.
The insert button is designed to assist with the license agreement, in not letting you inserting more than 250 tracks (yes, this plugin probably breaks that agreement, but as there is another one acknowledged below which also does, I’m hoping it’s ok for plugin/discovery purposes - it’s so ridiculously hard and unreliable to search using the Roblox site that I felt the need to start making this).
Ir provides filtering in the following ways, if you can think of any more useful filters to add, I might add them.
It’s designed to be really helpful for finding good tracks, if you find a track you like and want to know if the library or album has anything else you might like in it, you an right click the item to open it’s info panel, and then right like on the genre, library or album to quickly search for other tracks in that library/genre/library.
It will also attempt to automatically find variations of sounds (How they are often labelled track A, track B, track C etc.)
I tend to be quite bad at spelling so if you see any mustaks, please let me know 
I’d love to hear you’re feedback on this.
[Note: I am aware of Crazyman32’s similar RbxMusic plugin, I didn’t originally make this in direct competition, I started last July, It’s just taken me lots of spread out small chunks of sudden work to get finished - it’s the need to search for music for a game I’m working on which encouraged the for this final step to come to be. Somehow I have 397k tracks, where his has 372k which I’m not too sure why. I’m a bit stubborn financially in not wanting to shell out R$120 so continued to finish mine off, to a style of my choice )
