When you compare the cost of that $1 to what you can buy CDs for (I can get a lot of the CDs I want for $8-14 on Amazon.com) that $1 is too high given that you don't get it in a physical medium with the packaging and it's a lower quality audio format.

That's my main reason for disagreeing with the $1 for every song regardless of demand at the current quality offered. $1 should be a high quality compressed file at the very least.
