Heya! Sounds like a fun project! :)
If you don't want to do a recurring thing like Patreon, you are welcome to "buy" the loop bundle as a donation as well at whatever amount you feel is fair. Patreon is great because I offer a new song or two every week for people, but I understand that a repeating commitment like that isn't for everyone.
If you do subscribe to the Patreon though, you're welcome to use the songs after you stop subscribing. I don't want to police how people use the music, just make avenues for support me to make more music in the future :)
Feel free to reach out if you have more questions, happy to chat about it!
