How to Get Free Music Legally for Android
Use the built-in browser
If you are looking to download free Mp3 files from the internet (assuming it is a legal source), the procedure is the same as it is for downloading music on your computer. Fire up your Android browser and navigate to the website where your desired songs are available for downloading. Simply long press on a song link and choose ‘save link’ from the pop-up menu.
If you have not set your browser as the default app, you might be prompted to select a browser app to continue. Simply tap on the default browser app from the selection box and your download will begin. You can monitor the progress of your download from your notification bar and once the file is downloaded, you can either refresh your music library from your favorite music player app or run the file manually from the downloads section.
