Hi Community fellows 
One more cool update is here 
It was a really long-awaited feature and now bulk upload option is available in our Audio Player and Background Music apps.
It means that you can upload multiple tracks at once 
Feel free to share your feedback regarding this feature. Your opinion is always important to us 
Can we apply the same image to every track in a bulk process?
Hi @user3449 and welcome to Community
I have to say that bulk upload is available only for tracks, but not for images. So, the only workaround is to add the image to every track manually. I am so sorry 
I agree that this functionality would be really helpful for such use cases. Would you mind sharing your idea in our Wishlist?
We’ll try to consider your idea in our future updates
