No, that’s not a typo. I just downloaded about 100. You need to install the Amazon mp3 download application (free) for this to work. Here at my house the downloads are extremely fast, about 4 seconds per song, so that shouldn’t be a concern unless you’re on a slow connection.
examples: Jeremy Enigk’s OK Bear, Mogwai’s Christmas Song, James Pants‘ (from Spokane!) This Christmas Girl
