There's a JP musician whose work I really love. He sells his songs for $2 apiece online. This is all well and good.
But a while ago, he uploaded an alternate version of one of his songs, and I've found I like it way more than the original. Problem is, he never put it up for sale (and also the quality is low.) So, I want to send him a message on Twitter and ask him if there's any way I can buy it in high quality.
The only thing I can think of is asking him if 買い方がありますか, but that really doesn't sound right at all.
