I've implemented a few tie-ins with Facebook:

- if you share the link to a song's SomeSongs page on Facebook people can play the song right on Facebook!
- if you haven't signed up for SomeSongs yet, you can sign in using your Facebook account, which is very easy, just click the link up there
- if you have signed up in the past and you want to be able to sign in using your Facebook account (so you don't have to worry about remembering your SomeSongs password) you can connect your Facebook account to your SomeSongs account in the "My Info" section
- once you've got your Facebook account tied in to your SomeSongs account, you can opt in to have SomeSongs publish a story saying "So and so rated 'Song Title' on SomeSongs" to your Timeline when you rate songs, which is neat and helps get the word out about the songs on here and about the site
