I've been listening to Folk Alley (www.folkalley.com) online radio from Kent, OH... They post listings of the Top Rated Songs (by vote average, which is changeable as votes come in, and by vote total, which is a more constant list.

As I write this, the list of Top Rated Songs includes Arlo at #8, with "Highway in the Wind," and Sarah Lee and Johnny at #18, with "Holdin' Back"

You have to be a registered member to vote, but they won't hassle you with emails or anything like that.
