My item got rejected and I really don't know why


I created a lyrics script and uploaded to CodeCanyon but it got hard-rejected. I really don’t understand why, the mail says " Hi Cem Ekkazan,

Thank you for your submission. We have completed our review of “Lyrica - Lyrics Web App” and unfortunately we found it isn’t at the quality standard required to move forward, and you won’t be able to re-submit this item again.". Demo is here: why it could got rejected?

Your item was looks awesome, quality team doesn’t reject the item without any reason, please self analys the item again and make it best again. And please don’t send the item without making changes. All the very best for next submission.

Thank you very, when I’m contacted with the support team, they send me bunch of articles about design trends but I don’t think the design was the main problem, I think my product looks good enough. I will try some changes to submit again, I hope I can make it.
