Amazon.com has a bunch of free MP3s for you. A ton. 3,212 songs, in fact. The categories are these:

• Bestselling
• Song Title: A to Z
• Song Title: Z to A
• Artist: A to Z
• Artist: Z to A
• Album: A to Z
• Album: Z to A
• Time: Short to Long
• Time: Long to Short
• Price: Low to High
• Price: High to Low

I’m not sure what to choose. What I really wanted to see was something about “Music Taste: Good to Bad” and “Music Taste: Bad to Good” … but they don’t have that.

Kidding.

But anyway, not sure anyone is interested in this, but figured I’d mention it. And yes, they have some classical music. I see Mozart listed, for one. Not everything is free, but there are a good number here. (I know nothing about the recording, though.)

Update
Yes, I’ve taken advantage now. I downloaded a few piano works I didn’t own already. I’ll continue to search ….
