Interesting:
For digital albums of seven tracks or more, most artists will maximize their earnings by charging $7 USD. For EP-length albums (six tracks or fewer), $4 USD is the sweet spot. But again, there are exceptions, and if you’re an established artist who has seen recent success charging $18 for your digital albums, go for it. However, in all cases, leaving “let fans pay more if they want” checked is key: fans pay more than the minimum a whopping 40% of the time, driving up the average price paid by nearly 50% (in fact, every day, we see überfans paying $50, $100, $200 for albums priced far lower).
