word I did this in high school too. but maybe instead or 5, bump it up to 10. and 3 or even up to 5 dollars could be reasonable.

but if it's demo like you trying to give out to labels or w/e then 4 tracks, but you prolly already know that.

but word i'd think 10 would be cooler. but if you DID do 5, iunno if 3 dollars would make someone buy it. Maybe only the people who really know your shit, or real coo with you. but if they never heard of you, 3 would be too much for only 5.

just my 10 cents
