When a band is submitting their tracks if there was an option for them to say tick a box say that the song would work for say Wedding films or arial footage, vlogging or real estate. then translate that to a way of searching for music - this would drastically help speed up finding a suitable track. Even break it down more so they could say this song would work with a wedding video which would include audio from the day or just that this song is about love or is a positive theme that would work with a video which is just music driven. what do you think?
