Of course, completely, without any problem!
I hope my music is useful to you :)

Tell me what's wrong with that and I'll try to help you :)
I know that this can be done even in web games made with javascript without any framework, because a client once asked me to make loops of this type for his game made purely in javascript. The trick was simply to have an audio listener so that when the playback reached the end point, it immediately jumped to the start point.
I would say that concept works for practically any engine.
I've been checking song by song and I don't notice anything strange, what engine do you use?
In godot it is extremely easy to configure it, in other engines, I don't know how to do it.
In unity I think there is some plugin that can facilitate this configuration
In any case, if you had to implement it, it is simple, you simply have to detect that the position of the audio, at the moment it reaches the endpoint (preferably measured in samples) jumps immediately to the startpoint.
If you need help with this, let me know.
As for exporting the song in fragments, I have no intention of doing so. This start/end loop points procedure I think is something much more standard. In addition, I did the audio projects with some audio plugins that I no longer have and I could not render them again.
Yes, I leave the extended versions only on my patreon.
I created the patreon as a way for anyone who wants to support my content to do so, in return I leave some exclusive content for them.
I'm not sure it's the best strategy in the world hahaha but well. Maybe I'll rethink it at some point, I think it would be better for me to leave the extended loops in itch by putting a higher price on them, although money is not really my priority right now.
Answering your question, yes of course, you can join as a pro member and unsubscribe. I think you will be charged the monthly payment. The Eula that I add to this content is that you have permission to use it if you have downloaded the pack as a member. You can download that pdf from there as well.
Oh yes of course, it's Creative Commons Attribution v4.0 International
I always configure the license in itch but this time I forgot
By the way, I prefer to call them music pack, because they are really loopable assets for video games, although I always take advantage of the work and publish the same music in album format on platforms like Spotify etc.
That's a great reference! I'm happy to tackle a track in that style.
For future requests and ideas, I'm now managing all suggestions through my Patreon. I just created a new post there to properly handle all these requests, so feel free to add your suggestion there if you'd like, no pressure at all! It's the best place for me to see what to work on next.

Thanks again for the awesome idea!
