How to Set Up Your Account with Yahoo! Music Unlimited
In order to subscribe to Yahoo! Music Unlimited, you'll need to establish an account.
In the Yahoo! Music Jukebox, click Y! Unlimited in the left navigation pane then click on the signup link. You can try out Yahoo! Music Unlimited first before committing to a full subscription. If you have a Yahoo! ID, you'll next be taken to the account set-up process. If you don't have a Yahoo! ID, you'll be prompted to sign up for a free Yahoo! account, and then you'll be taken through the Yahoo! Music Unlimited setup process.
In addition, you can also set up a Y! Unlimited account whenever you click a feature or service that requires subscription. For example, if you click Add to My Music next to a song you like, you'll be offered the opportunity to sign up for Y! Unlimited to enjoy that song.
You can always buy individual, burnable downloads whether you have a Y! Unlimited subscription or not. For this, you simply need a Yahoo! ID and Yahoo! Wallet account. You'll be walked through this process if you click the Buy button next to music.
