[soundcloud] --no-playlist parameter doesn't work with soundcloud sets

[pricejn2]

When using the --no-playlist parameter with soundcloud set, all songs in the set are still downloaded:

youtube-dl --verbose --no-playlist -o '~/%(title)s_%(id)s_%(extractor)s.%(ext)s' 'https://soundcloud.com/umf2014sets/sets/ultra-music-festival-2014'

This is expected behavior as explained in --help. What would you expect from youtube-dl to download when you pass --no-playlist along with playlist link?

[pricejn2]

Expected because help only references videos?

--no-playlist
If the URL refers to a video and a playlist, download only the video.

I guess I was expecting it to either download nothing with a message that this is a playlist or perhaps the first song in the set (I understand I could use --playlist-end 1 for the latter behavior)

[dstftw]

Expected because https://soundcloud.com/umf2014sets/sets/ultra-music-festival-2014 is a playlist URL (and not a single media URL) without any ambiguity. For example, https://www.youtube.com/watch?v=pBhT_CINPjE&index=2&list=PL6ggZGXwREC2FV8Ms17KRWZ8_jf0U79cr is ambiguous as it contains a video part v=pBhT_CINPjE and a playlist part list=PL6ggZGXwREC2FV8Ms17KRWZ8_jf0U79cr. When you download latter URL without --no-playlist it will treat URL as playlist URL and download the whole playlist. If you'll pass --no-playlist it will treat URL as video URL and download only single pBhT_CINPjE video.
