It's to make sure that you buy more than the single song that you want. They will probably sell packages of 100, 200, etc. points. So, if you want to buy 10 songs at 9 points each, you'll be left with 10 unspent points. What are you gonna do? Purchase another package because you don't want to let these points go to waste.
