[WIP]
Using the Cantonese Fonts, you can read all the Chinese lyrics with Jyutping when listening to Spotify on web browsers. The process is the same as using the Cantonese Font for any other website.
Procedure
The general idea is to use an extension that lets you override the lyrics’ default font with the locally-installed Cantonese Font. The next section shows you how to do that with different browsers.
Note that the Spotify web-app is built so that it is not possible to copy content out from the browser window.
Google Chrome
1. Install Stylebot
2. Activate extension for Spotify
3. Apply rules for the lyrics
[data-testid="lyrics-container"] p {
font-family: "VF Cantonese";
font-variant: "Medium jyutping";
font-size: 72px;
}
