Blazify

Blazify is a music player for Android devices, built with Kotlin and Jetpack Compose. It streams from YouTube Music as you want, keeps what you want for offline listening when you do not have internet, and follows the words as they are sung, with no ads, no disturbance and no account required. You can sign in with Google for better song recommendations if you want to, and there is no tracking. Nothing is sent anywhere except to the services you turn on yourself.

Listening

* Millions of songs, searched by name or found by browsing: songs, albums, artists, playlists and videos
* Gapless playback through Media3/ExoPlayer, with the next track prepared while the current one is still playing
* Download anything for offline listening, or let it keep songs as you play them
* Play the music already on your phone, beside everything else, in the same queue and the same player
* A queue that you can reorder by dragging, save as a playlist, or start a radio from
* Sleep timer, with an end-of-track option so it never cuts off mid-song
* Don't play this song: keep a song out of queues, radio and suggestions
* Double-tap to seek on every player, and podcasts that keep their own speed
* A Quick Settings play/pause tile, and shortcuts for Liked, Downloads and Shuffle
* Save data on mobile networks, and download only on Wi-Fi

Sound

* Ten-band equalizer with a live frequency-response curve and 13 presets
* Preamp control, each preset pre-compensated so boosts never clip
* Bass boost, surround and reverb
* Volume levelling, for queues that mix a record mastered in 1975 with one mastered last year
* Skip silence, playback speed and pitch

Lyrics

* Time-synced lyrics with word-by-word highlighting
* Several sources asked in an order you choose, because no single one has everything
* Translation and romanisation, for singing along to a script you cannot read
* A full-screen view, and lyric cards you can share as an image

Look and feel

* Material 3 with Material You dynamic colour
* Colour taken from the album artwork, accent only or the whole screen
* Several player designs to choose between, with a live preview while you pick
* Light, dark, pure-black, or whatever the system is doing

Library and sharing

* Liked songs, listening history, your own playlists and a Top 50 built from what you actually play
* Listen Together: share a room code and play in sync with friends
* Playlist import from a file or a link
* last.fm scrobbling and Discord presence, both optional and with your own credentials
* Music recognition: hold up your phone and name what is playing
* Android Auto and home-screen widgets
* Back up your whole library to a single file and restore it on another device

Privacy

Blazify has no advertising, no analytics and no tracking libraries of any kind. Signing in is entirely optional. Everything except your personal YouTube Music library works signed out.

One thing worth stating plainly, because it is the only time the app sends anything about your own files anywhere: when you scan the music on your phone, any track whose file carries no cover art has its title looked up online so a picture can be found. Files that already have artwork are never sent. It can be turned off, and turning it off only costs you the missing covers.
