All Time Low have unveiled a brand new single by means of sending one of their fans a birthday cake.

The track, aptly titled Birthday, is currently only available via a special Dropbox link, having been delivered by mail to a fan who unsurprisingly shared the news to Twitter.

Birthday is a sickly sweet slice of pop rock which sounds like All Time Low doing what they do best: having fun, rocking out and sounding good while they do it. You can listen to and download Birthday here, and you can check out the cake they sent fan Mia below.

All Time Low are currently touring the United States for a limited amount of shows as they take part in select editions of the final Vans Warped Tour.
