Children Of Bodom have taken a very interesting marketing approach with their new album, Halo of Blood. Their lead single has been playing on radio for a few weeks, but the band have not released the track online as a stream and have been vigilant about taking down Youtube videos.
Now the band has released a second single, Transference, via iTunes.
If you pre-order the band's new album on iTunes, you will instantly download the new track. The album doesn't come out until June 11th so there is some time.
I did a bit of internet sleuthing, and found somebody who posted a Youtube stream of the song, but chances are highly likely that this will be taken down as well:
