music sites can be used for URL music , only these?

[broforce1]

ok,so u know that to apply music u must use URL from another website to work,
u can browse Newgrounds
and also maybe Freemusicarchive
i think these only websites that u can use them
i dunno if u gonna understand me but who tried to make music with triggers ok
just put music and a region then thing to activate the trigger and ad URL so go to this website https://www.newgrounds.com/audio/browse
u can find a bunch of musics,view one of them and copy the link address above the page then paste the URL
on the music where it says URL if u select the music in level editor..but also some music are not working
and yep,sounds a stupid question but,why we mostly allowed only to use this website,cuz logging in to these sites
are so difficult and it wont show any way to complete any validation,so there is much easier websites to be used
and log in to it,so why we don't use more websites u can upload music from more,and i got idea,what about to ad music list and upload music audio music in it on Plazma burst 2 website..
