This is a bit of a silly request, but since SE has recently been posting their Podcasts on soundcloud, I feel like I now have a legitimate reason to bring this up.
Would implementing oneboxing support (a la facebook) for SoundCloud tracks be quite difficult? Basically, similar to the way Wikipedia oneboxes, with a track title which links to the SoundCloud page, album art pulled from SoundCloud, and some track info (length, genre, title, tags) would be ideal. Or, even just a static image linking to the track page would be nice to have.
Example (click here for larger image):
What's great about Soundcloud is that they have an entire section of their site dedicated to community developed apps that use Soundcloud's API for all kinds of different things, and there's even an area specifically for developers for anyone looking to incorporate Soundcloud into their own app.
I don't know if any of that would actually be useful for this, but it still says something about the company.
