To positively vote for a song, you need to listen through Live 365. The player on their site has a couple small cartoon hands in the upper left corner - one giving a thumbs up and one giving a thumbs down. Clicking on the thumbs up counts as a vote for that particular song. I haven't experimented with it enough to know if clicking it lots of times means lots of votes, or if it's just one vote per person per song.
Since we have such an extensive on-air library, the top ten list changes almost every day during November, as all the music gets added. By December, the library is pretty much set, though there's still a lot of fluctuation from one week to the next. I'll do my best to post new lists on Friday's, so make sure you check back!
And if you want your voice to be heard, just listen to the Sounds of Christmas through Live 365, which you can do right here: http://www.live365.com/stations/soundsofchristmas
Thanks so much for listening! And may you always believe in Santa Claus!
