This is what podcasting was invented for - They Might Be Giants have a podcast, and it's offering exactly the kind of material that used to be on their Dial A Song. Subtle evidence that podcasting will replace using the phone to get audio information, perhaps?
The first track on this album would probably not have sold too well, but that's what used to make They Might Be Giants so amazing. I've always thought their better songs to be the whimsical ones. But some of this stuff borders on comedy, as with "Turtle Songs of North America."
I don't know how often they're going to offer podcasts, but when they do, it'll be like a little album each time. How they'll make money off of this, I don't know, but should that always be what motivates people to do creative work?
