Track Link : Spotify : https://open.spotify.com/track/4WMHDpmfuLwM2Ty8KQXZjN Actual Media URl : https://aac.saavncdn.com/201/f2472e5f1e27a80b11773e88628dc06e_320.mp4
-
Steps to Reproduce:
1.Play this Spotify link without seeking the track. The stream automatically dies at the0:44timestamp and only occurs for tracks mirrored through JioSaavn.
2.If I play the actual media URL as an HTTP track via my bot, it plays fine. This issue only occurs when the tracks are mirrored through JioSaavn.3.The media file extension is.mp4, so I used anMpegAudioTrack. -

Could you test to see if this is still an issue even after 2fc96d70b9f632ceb7b8387b69a874cbf86c05c0?
