7s er 8s er something?
If, I had to have one complaint, it would be that the build up (or whatever the correct term is for it) is a bit slow. Not in tempo, but as in the time it goes before adding a new element to the beat, if that makes sense.
Nonethless, I like it. Great background music while I'm reading. ;)
Please contact me if you would like to use this in a project. We can discuss the details.
