Piano music loop

10 music loop, played on 1 type of piano,9 of the 10 tracks are 21 seconds, perfect for visual novel games.
1 to 7 can be attached to each other, to create diversity in my coding it look like ( loop 3 time, after random 1-7 then loop 3 again, ect) 8 and 9 can also do that but there is just 2 of that type . ans the 10 is experimental. I've already wrote that in the read me.

You can use commercially when giving me credits about it. remix/modify/ect
