Brew Stable Version (v2.5.0) Behind Source Main Branch (v2.6.4).

[nullmaxwell]

After a fresh install, brew info spicetify-cli returns the following:

spicetify-cli: stable 2.5.0
Command-line tool to customize Spotify client
https://github.com/khanhas/spicetify-cli
/usr/local/Cellar/spicetify-cli/2.5.0 (54 files, 8.1MB) *
  Built from source on 2021-09-22 at 17:35:14
From: /usr/local/homebrew/Library/Taps/khanhas/homebrew-tap/spicetify-cli.rb

The spicetify-cli.rb on line 4 references v2.5.0.tar.gz explicitly and should be updated to reflect the most current version of spicetify-cli which is at v2.6.4 as of this posting.

Special mention to this issue on the spicetify-cli project that initially raised the issue.
