Certain tracks from SoundCloud cannot be played

[Softvision-CristinaBadescu]

[Notes]:

• I've encountered this issue for certain tracks such as: https://soundcloud.com/jahseh-onfroy/fuck-love-feat-trippie-redd, https://soundcloud.com/flameemojimusic/i-get-the-bag-feat-migos, https://soundcloud.com/kodak-black/roll-in-peace-feat or https://soundcloud.com/a-boogie-wit-da-hoodie/drowning-feat-kodak-black-1.

• Also, if you open the browser console, after a couple of seconds, you'll see "ERROR: loading timeout". See the screenshot below:
  

• If a song is already playing, send the specific track to the player (using either "Play Now" or "Add to queue" option), select "Next" button and you'll encounter the "NaN:Invalid Date" message; also, the progress bar is displaying the previously track's progress.

[Affected versions]:

• Firefox 58.0 and up

[Affected Platforms]:

• All Windows
• All Mac
• All Linux

[Prerequisites]:

• Have a Firefox profile with the latest "Min Vid" add-on version (v0.4.7 custom build from 2018-01-29) installed.

[Steps to reproduce]:

1. Open Firefox browser with the profile from prerequisites.
2. Navigate to https://soundcloud.com/flameemojimusic/i-get-the-bag-feat-migos.
3. Click the "Play now" button.
4. Observe the behavior.

[Expected result]:

• The track is sent to the player and starts playing.

[Actual result]:

• "Loading audio from soundcloud.com" is shown for indefinite time.

[Additional notes]:

• I've waited 5 minutes for the track to load and start playing, but it didn't happen.
• In order to overpass this issue you need to close the player and send other tracks to the player.
• This issue is also reproducible with the latest Min Vid version from Test Pilot experiments page.
• Here is a screen recording of the issue:
