Hi! The Maximum Chill Humble Bundle is currently the only bundle I have running, but there are more planned for the future. Dates and content have not yet been assigned, but if you want to keep up to date on when my music bundles are out (or when my music is part of another bundle), the best place to do so is on the Game Asset Bundle Discord.
Here's an invite: https://discord.gg/JmReCPPGZz
