When I tried to share videos being played back with a non-alphabetic song title or artist name to SNS, their URL's became as follows.
There is no problem with alphabetic song titles.

It would be appreciated if you would fix it.
If it is difficult to fix it, then could you let me know which file restricts characters in URL?
In this case, I think it can fix it myself.

In addition, I have the following requests:

1. While playing back, I'd like to play back videos by default.
2. I'd like to reflect a song title etc. that is being played back.

Finally, I did not pass Amazon's appraisal, but did I pass your appraisal?
