I think when I started out a band was lucky to make $.75 off a $12 cassette sale (pre-cd's). And that was only after enough sales to pay off what typically amounted to a $200-500,000 loan from the record label. Divided by $.75, that's a LOT of albums to sell before making so much as a penny. So the sweet spot to me is a much lower spot than $5. Realistically, as an artist I would be very happy to make a $1 profit on a $1 album download rather than MAYBE making .$75 off a $12 album sale. And I think as a fan I ALSO would rather buy 10 hot new albums for $10 than pay $10 for a single album. It's kinda like watching Borders bookstore closing. The last days when discounts hit 80%-90% off were RIDICULOUSLY busy, and the bookshelves were emptied. Yet when sales were at 50% off, it wasn't nearly as busy. When you hit that magic price point, you'll know. You just might be unhappy that the price is much lower than you were hoping for.
