Mini-trailers are great to get an impression of a game at a glance. It would be awesome if the soundtrack experience could benefit from this tech as well.

Currently many soundtracks do not have a trailer at all, there is no on-platform way to sample the music if you don't own and have played the game already. I imagine something could be generated from the album cover and active parts of a number of tracks. Possibly render a waveform as an overlay if it feels too simple.

I collect and listen to game music, as I listen to it while coding both at home and at work, so I buy a lot of the soundtracks without having played the games, thus the lack of trailers is a real pain in the behind and it forces me to search for the music elsewhere, just to get a preview.
