Genius Button (Spotify + SoundCloud) από Txxicu

Adds a Genius button directly into the Spotify and SoundCloud players.

How it works:
• Spotify - a Genius icon appears next to the "Lyrics" button in the now-playing bar.
• SoundCloud - Genius icons appear next to the "Share" button on track pages and next to the "Next up" button in the bottom player.

Click the button and the extension:
1. Reads the current track title and artist from the page.
2. Queries the Genius search API.
3. Opens the found song page on Genius in a new tab. If nothing is found, it opens a regular Genius search page as a fallback.

The tab opens instantly, so the click always feels responsive even if Genius responds slowly.

Privacy: the extension collects no data. It only sends the track title and artist to genius.com to perform the search.
