One really amazing thing that would be a really nice addition to the webflow CMS is audio files. Also, a SoundCloud player would be really amazing as well. If we only had one to start, I would definitely want the SoundCloud player.
I own a music production company and was wanting to build it with webflow BUT the lack of either of these options is making me think about an alternative option.
UPDATE: I just realized that there are a few options for embed SoundCloud into any website. I'm sure there are sexier players out there though.
