Go to Your Collection and check the box that says “For Trade” next to the albums you’re willing to offer for trade. Next, browse the marketplace for something you want to trade for. Click “Offer Trade” on the album page, and a window will appear letting you select the list of albums in your collection that you’re willing to trade for the album you want.
To increase your chances of a successful trade, add a lot of albums to your offer. All trades are one-for-one, so the other collector only gets to pick one of the discs in your list. If someone accepts your offer, we’ll notify you via email.
Important note: If you’ve downloaded an album, you cannot subsequently trade it.
