Hi,
mhmh… the fact that a track was used somewhere else does not necessarily mean it sounds good objectively, or by the reviewer’s standards. The same goes for so-called “pro” stuff: No one cares about an old Otari these days, especially not in a stock market like this where it’s all about in-the-box mass production. As far as the actual rejection text, it is simply a pre-written message that may not reflect the actual problem the reviewer saw. I doubt it was something as simple as a cymbal - that should have resulted in a soft rejection. Unfortunately, you can’t contact them about this, this is just the way it works.
Regarding your track, it’s impossible to tell why it was rejected without hearing, so you might want to upload the track so SoundCloud so that people can listen and give you some feedback and tips. Or even better, show us the tv-spot! Good luck.
