v7.0.9

- Extract year from releaseDate using substring(0, 4) in both hooks
- Add year field to templateData in single download functions
- Add year field to templateData in bulk download functions
- Allows parseTemplate() to correctly replace {year} placeholder instead of defaulting to '0000'
- Fixes folder structure generation when year is used in filename or folder templates

+## FAQ
 
-> Every coffee helps me keep going
+### Is this software free?
+
+_Yes. This software is completely free.
+You do not need an account, login, or subscription.
+All you need is an internet connection._
+
+### Can using this software get my Spotify account suspended or banned?
+
+_No.
+This software has no connection to your Spotify account.
+Spotify data is obtained through reverse engineering of the Spotify Web Player, not through user authentication._
+
+### Where does the audio come from?
+
+_The audio is fetched using third-party APIs._
+
+### Why does metadata fetching sometimes fail?
+
+_This usually happens because your IP address has been rate-limited.
+You can wait and try again later, or use a VPN to bypass the rate limit._
+
+### Why does Windows Defender or antivirus flag or delete the file?
+
+_This is a false positive.
+It likely happens because the executable is compressed using UPX._
+
+_If you are concerned, you can fork the repository and build the software yourself from source._
+
+### Want to support the project?
+
+_If this software is useful and brings you value,
+consider supporting the project by buying me a coffee.
+Your support helps keep development going._
