for $10 or more, you get the album as your very own, instead of streaming. Not only will get a higher sound quality version, you'll know that your money is going to the artist (me!) and you can still take it with you anywhere! As a bonus, I'll throw in a sticker and you can share the download code with a friend! 

for $20 or more, you get to hold something in your hands, gaze at the cover art, and read liner notes. You also get a bonus track that is only available on the physical album. As a bonus bonus, I'll throw in the digital album and a sticker! Yay!
