This is something I had been thinking about before a bit but I didn't see evidence of it until just today. It's not really a big thing, but it's a thing.
The problem is timed releases. As in, they're pretty much impossible.
A Day To Remember's new video for "I'm Made Of Wax, Larry, What Are You Made Of?" is debuting next week on MTV2. This has been pushed pretty heavily by their respective sites and by MTV2.
Now, the song itself has been floating around in various stages of RBN testing for maybe a month or so. I imagine it would be good for sales of this track (and, by proxy, sales of other RBN tracks) if it were able to coincide with the video premiere. If the track had been done in-house by HMX, it would have been possible to set it up like that.
As it stands, the song just moved to Peer Review. To me, it's ready for the store. It needs 7 more reviews though so we'll see. Maybe it works out right this time, maybe not. However it won't always work out the right way.
I wonder is if it's possible for labels/bands to try to put the tracks in wayyy early so they finish early and then HMX can hold them in limbo until a specified date...
