Librezam 제작자: FoxRefire

This is a browser extension that uses internal API of Shazam to recognize the music playing in the current tab.
Librezam also supports Audd and ACRCloud as alternative backends, which can be changed from the configuration.
Unlike other similar extensions, it works on almost all sites and has fewer bugs.

Requests unrelated to music recognition, such as telemetry, will not be made.
This is unofficial project and is not affiliated or supported by Shazam ltd.

!!Please report extension issues to Github Issue or ‘bqzfjohg@addy.io’, not in the review section, and read the troubleshooting below before reporting the problem !!
