Rejected!! Help please?

Hello,

Today i received a rejection once again and i’m confused what is meant by: “This item does not meet the general commercial quality”. Since the e-mail suggested i go to the forums for feedback, here it is:

Hopefully you guys can help me out here. Is it mixing? Mastering? Composition itself? I’ve had other items approved in the past that were less quality wise in my opinion.

It’s so confusing to get these rejections without a specific direction.

Thanks in advance!
