zotify-genre-tagger

For when you forgot to enable genre tagging in Zotify. This crate will run through a given folder and use the .song_ids files that Zotify leaves in each album's directory to look up your songs' artists' genres on Spotify and tag each file appropriately. Spotify only currently assigns genres to artists, not individual songs. This is the same thing Zotify would do with both the MD_SAVE_GENRES and MD_ALLGENRES options enabled and MD_GENREDELIMITER set to ",".

Configuation

You will need to create a Spotify API key at the Spotify for Developers Dashboard.

Use a .env file or pass as environment variables:

RSPOTIFY_CLIENT_ID={your Spotify client ID}
RSPOTIFY_CLIENT_SECRET={your Spotify client secret}
BASE_PATH={wherever you pointed Zotify at}

Currently only takes as input .ogg files (which is what Spotify uses natively anyway) and only outputs .ogg files (with an Opus encoding to save space). This can be changed in the ffmpeg remuxing section at the bottom of main.rs.

Usage

Then, just run zotify-genre-tagger.

Building

This uses a nightly Rust feature, #![feature(closure_lifetime_binder)], so you'll have to download it with rustup toolchain install nightly and then switch to it for this project with rustup override set nightly.
