Id issue from pulling youtube Id in Custom soundscape

[Eroenex]

Ok I been using it and found and issue, was looking through the GitHub and wasn't mentioned so decided to post an issue.

I been noticing when relating to pulling id from youtube id, it does not allow playable links with id with ( dashes - and underscores _ )

Issue Example 1:
https://www.youtube.com/watch?v=Z04PUm6_Xd8

So the Id is : Z04PUm6_Xd8

When you put it into the Custom soundscape it doesn't work because of the underscore _ (Between 6 and X)

Issue Example 2:
https://www.youtube.com/watch?v=EexqF4tz-8U

So the Id is : EexqF4tz-8U

When you put it into the Custom soundscape it doesn't work because of the underscore - (Between z and 8)

Conclusion:
Im not sure but I think I see a possible missing syntax symbol errors for the lack when comes to dashes and underscores
