Apple rejected my app

So, do the next step as instructed:

"If you believe your app is compliant with the App Store Review Guidelines, you may submit an appeal."

...and go from there. Your explanation above should be part of your appeal.

Good luck.

I am not a lawer or have no relationship with any members or representatives of App Review team, but if I were to interpret the terms Apple had shown to you...

Apps should not facilitate illegal file sharing

Which means, you need to prove all the sites from which users can download is legal. Wheather having donwload button or not is irrelevan to legality.

without explicit authorization

The term "explicit autorization" usually means some sort of documents, hard-copied or electrical. You need to get a document which states your specific app is autorized to use the contents of the site from every site where users can download contents, and send all the documents to Apple. Again, wheather having donwload button or not cannot be an "explicit autorization".

You may ignore my iterpretation , I cannot be any sort of responsible for that.

Thanks for your clarification.

I also cannot understand why there are so much apps with the same functionality in App Store and they have not rejected or deleted.

I cannot give you any advices about how to get similar apps to be approved.

But as far as I have heard from other developers till now, (I have no experience that apps I have involved in development were rejected,)

appealing that there are other Apps of the same functionality on the App Store, just makes you receive a simple reply like:

We are reviewing your app based on the Review Guidelines.

Once rejected, it is hard to overgo Apple's Review.

>cannot understand why

No apps in the store now are any indication going forward if app review will/won't reject or approve yours. The ASRGs are fluid and change over time.

Did you file an appeal? Stick w/the process. Don't waste more time here until you do that as next step.

I suspect that app review will continue to reject (or ignore) your app because:

".....users can......download music from websites that allow to do it"

is no guarantee that the download does not violate copyright, only that the website is allowing you to download it.

Indeed. They could easily browse to a rogue web site that has tons of illegal content to download. There's no way your (the OP) app can prevent this.

You might have to restrict your app to ONLY allow downloads from legit sites and have some proof of this.

What is condition of your app status ..Is it published now ?

Cool. So how Chrome ensures the content you can download is legit? Chrome is downloable from App Store.

The subject for Apple is not to serve you but to serve them... I quit this platform for alternative. Bye

Bye. Hope for you grass is greener elsewhere… 😁

I am not a lawyer, but I'm pretty sure that just because the website (an online service) allows end users to download some music (provides a "download" button) it doesn't imply that other parties (you) are allowed to create software that utilise that button automatically. These are probably online services, with Web user interface, meant for end users, probably with some Terms of Service that these end users are obliged by.

In my opinion, it's similar to a case when a web app has (private) REST API that is used by its frontend client. The fact that such a private API exists, doesn't imply that a third party can create and distribute software that uses that REST API. Technical possibility to do something does not mean that you can do that thing.

In other words, I believe that Apple might be correct by saying that "[you lack] authorization from the relevant third-party sources". You assumed you don't need this authorization based on existence of "download" button, while that assumption might me incorrect.
