Add some music to get started

Pick your whole music folder at once — MP3, M4A, WAV, whatever's in there. Everything plays straight from your phone, nothing uploaded anywhere.

What you can do here
•Play everything in the folder you pick - offline, with shuffle, repeat, crossfade and an 8-band EQ.
•Keep playing with the screen off: the lock screen, the shade player and the home-screen widget carry prev / play-pause / next, and a paused song starts again from there without opening the app.
•Lyrics that follow the song - word by word or letter by letter - plus a sleep timer.
•Your own playlists and albums, cover art you can fix, and a Studio for recording and chopping mixes.
•Back up everything to one .zip and restore it on a new phone.
•Not sure about something? Settings → Important lists every feature in plain language, and Settings → Support has an assistant that knows the app and works offline.

💿 How to get a song
New here? There are two ways in. Either let the app make the file for you from a Spotify link (steps 1-3 just below), or bring music you already have with + Add songs (the last note here). Both end up in 🎵 Library → All Songs, saved on your device with no ads.

1. In Spotify, tap Share → Copy link on the song to copy its link.
2. Tap 🎛️ Conversion Tools below — a drop-down opens. Open the built-in converter below (🎵 Spotify to MP3), tap the link box to paste the link and tap Convert.
3. That is it — when it finishes the song is already in your library (🎵 Library → All Songs), keeping its title, artist, album and cover art. Nothing to import. Want the file on your device too? Tap ⬇ Save the file too.

💡 Audio formats explained
MP3 — the everyday format. Compressed, small files (about 1 MB/minute), sounds great on most speakers/headphones. Best for phone/device storage.
WAV — lossless, uncompressed. The highest quality but huge — roughly 10 MB/minute (5–10× an MP3). Best when quality matters more than space (editing, archival, hi-fi).
AIFF — Apple's lossless format. Same audio quality as WAV in a slightly tidier container; every converter in the app can write it.
FLAC — lossless but much smaller than WAV (~5 MB/minute) while keeping all the detail. Great middle ground if your device plays it.
These four are exactly what every converter in the app can encode to — nothing is listed that it cannot produce, and nothing it can produce is missing from the lists.
Rule of thumb: if you're just listening, MP3 is more than enough and keeps your library small. Only pick WAV/FLAC when you want lossless and have plenty of storage.
💡 Backup: if the in-app converter can't find the song
These open your link pre-filled — convert there, download the MP3, then import it with + Add songs → + Files:

🎵 Spotify to MP3
⚠ Experimental — Paste a Spotify song, album or playlist link below, pick your format (MP3, WAV or FLAC), and convert — done right in the app. Albums and playlists resolve their real track list, then you choose whether each song saves on its own or everything lands in one ZIP — every file keeps its real name, artist and cover. Lossless by default: output is FLAC (every bit of the audio, about a fifth of a WAV\u2019s size). Pick MP3 if you would rather have small files.
🎬 YouTube to MP3
⚠ Experimental — Paste any YouTube URL, pick MP3, WAV or FLAC, and convert. If your format can't be produced, it falls back to another one automatically.
🎞️ MP4 to MP3 Converter
⚠ Experimental — Convert MP4 video files to WAV, FLAC, or MP3 audio directly in your browser. No upload needed, everything stays on your device.
🔗 Expand URL
Paste a short Spotify link (open.spotify.com/s/...) to get the full track URL. Note: If you already have the full open.spotify.com/track/... URL you don't need this step — it's just a fallback for short links.
