Well, how about that. My album, Penmachine Sessions, is now available at the iTunes Store. When I tested it, the individual tracks didn't show up, but if you're not using one-click purchasing, you can add it to your shopping cart and then look in there to hear the previews. I hope they'll sort that out shortly. If you've already listened to or own my stuff, I'd sure like it if you wrote a review at iTunes.
A couple of notes: (a) The album should also be available at some of those other music services that hardly anyone uses fairly soon too. (b) Here's a secret—you can download all the songs in MP3 for free from this website. But if you want to buy them too, or grab a physical CD. I'd appreciate that!
