InterTune

InterTune is a fork of OuterTune , which is itself a fork of InnerTune . It is both a local media player and a YouTube Music client.

Features:

YouTube Music client with song downloading for offline playback, background playback, no ads, and account synchronization

Local audio file playback (MP3, OGG, FLAC, and more)

A custom tag extractor rather than MediaStore's metadata extractor, so tags delimited with a backslash show up properly

Play local files and YouTube Music songs in the same queue

An offline tab listing the songs already cached on the device, so you can see what will play with no connection

Integrated library screen design

Multiple queues

Synchronized lyrics, including word by word and karaoke lyrics (LRC, TTML)

Audio normalization, tempo and pitch adjustment, and other audio effects

Choose where Quick picks comes from: YouTube Music, Your library, or Best recommendations, which builds the row on your phone from how you listen

What's playing? names the song around you, using Shazam, and can fill a playlist with what it hears

A home screen widget that takes the shape of its size

Spatial audio on any headphones, with head tracking on supported ones

Android Auto support

What it connects to:

YouTube Music, for everything you search, play, download or sync. Signing in is optional.

LRCLIB and KuGou, to find lyrics for the song that is playing. Each can be turned off.

Shazam, only while you have it listening. A sound fingerprint is sent, with the time and your time zone, never the recording. The cover of a song it finds is loaded from the address Shazam gives.
