Hi there! I understand that when you try to download a song through the MyTunes app by clicking Save/share, you end up with a completely different file than expected. That sounds confusing. Let's get to the bottom of this together.

To clarify:
- Are you trying to download a purchased song, or is it a free track?
- Is this happening with one specific song, or multiple songs?
- When you say a different file downloads, is it a completely unrelated song, or is it a file type that looks unusual?
- Also, what file format does the downloaded file have (e.g., .mp3, .ogg, .wav, or something else)?

Once I know more, I can suggest the best approach. Meanwhile, here are some initial steps that often help in similar scenarios on Android devices like yours:

1. Clear the App Cache
Sometimes, the app’s cache might cause mismatched file downloads. Go to your device Settings > Apps > MyTunes > Storage > Clear Cache. Then restart the app and try again.

2. Check for App Updates
Make sure your MyTunes app is updated to the latest version available on your app store. Updates often fix bugs like this.

3. Check File Associations
Since your downloaded file is different, it might be a file association issue where the app is linking the wrong file to the download button. Try opening the downloaded file with a different music player app to confirm what it is.

4. Logout and Login Again
Logging out of your MyTunes account and logging back in can refresh your session and clear minor glitches related to files and downloads.

5. Try Downloading from Another Network
Sometimes, network issues could cause swapping or incomplete downloads. Try switching from Wi-Fi to mobile data or the other way around and see if that changes the behavior.

If you’ve tried any of these already, please let me know, and we can try digging into advanced settings or checking if this is a known problem with the app right now.

Does this help so far? Could you share some details on the downloaded file type or what exactly you see? That will help me guide you better.
