This method is NOT the best buy one
- Download the Shazam app on your phone (method works on IOS idk about Android)
- Open the app and find the settings button
- Tap it and at the top there should be a free trial for Apple Music.
- I believe first time Apple Music users get 4 months and other users get 1 month.
- If you want to get another trial, delete the app and repeat the process.
You can also use a Web debugging tool like Fiddler to capture the code & you can sell it for profit.
