Let's get you back to your downloads. If you're still on the Saavn app, please head to your Playstore and download the all-new JioSaavn app.
If you're on the JioSaavn app, make sure you're on the updated version of the app. Next, restart your device, relaunch your app, and try downloading songs one more time. If that doesn't help either, please switch between cellular data and Wi-Fi, that should work.
For any reason, if you're still unable to download songs, please share a screenshot of the error message and we'll take it from there.
