Description

Some songs have png thumbnails instead of jpg ones. youtube-dl tries to download https://i1.sndcdn.com/artworks-000125923770-ozlgcz-original.jpg but the thumbnail is located on https://i1.sndcdn.com/artworks-000125923770-ozlgcz-original.png in this case.

Would probably be a good idea to fallback to a lower quality thumbnail if there's a 404 for a high quality one. In that case you'd at least get a 500x500 cover rather than an error.

SoundCloud doesn't really mention the existance of original artwork urls in their API docs, so I'm guessing that's why it's not always a jpg.
