Step 1. Get the files onto the phone
Use a USB cable, an SD card, or a desktop copy into the phone’s Music folder. Keep a simple folder layout (Artist / Album is enough). Mixed formats are normal: MP3, FLAC, M4A, WAV, OGG. You do not need to convert everything to one type first.
Step 2. Grant folder access
Android will ask a local player for permission to read music or selected folders. Allow it. If the library looks empty, the app is pointed at the wrong directory or permission was denied. Scan again after you copy new albums.
Step 3. Pick a local player, not a locker for rented audio
Any player that reads device storage can play a file. The useful difference is shuffle and library tools. If you want the whole collection, not the same commute loop, use a no-repeat cycle. ShuffleIt™ is a free Android download for that job: offline playback, true shuffle, optional one-time premium unlock. Details on true shuffle for Android and the Android product page.
Step 4. Shuffle the library you just scanned
Start shuffle on the full library (or on the artist/folder you actually want to finish). Do not shuffle a 30-song playlist and expect 2,000 other files to appear. Walk through how to shuffle without repeats if the old habit was random-on-a-short-list.
