In Music SE we can embed Youtube videos and SoundCloud audio to our questions and answers just by posting the link. Here's an example.
I think that feature would be very useful and convenient here.
I would suggest starting a collection of posts here that would be significantly improve by the addition of these features.
It sort of makes sense (allowing embedded sound on a 'Music' site), but we are always a bit cautious about activating multi-media content on these sites. The main source of traffic for this site will be search, so overly-gratuitous use of these features are essentially burying (potentially) a lot of content in black box that cannot be seen by search engines. So rather than guessing whether this will actual help or hurt this site, it is better to see how these features would be used in actual practice.
Including SoundCloud links does not change these statistics by much:
Thank you very much for the suggestion. I've sent a request to the dev team to enable embedding.
A short note
I took a look at data. Right now there are 674 not deleted questions with a link to "youtube.com" (out of 2.7K questions total). Among those questions I found that:
There are a lot of questions where a link to Youtube is used as a context. For example
They're both soundtracks. One is James Horner's OST to the film called 'A Beautiful Mind', while the other is an album composed by Jóhann Jóhannsson for 'The Theory of Everything'.
Also I've seen a lot of ID questions that link to Youtube. I even found a question where a video somehow got embedded and the question looks fine.
As a result in general I would keep without embedding videos the questions where a link to Youtube is provided as a context (like in the example above) because it might break the reading flow. On the other hand, ID like questions could benefit from embedding the content to the question page.
