Help me understand the reason for the refusal. Romantic guitar track

Help me understand the reason for the refusal. I was told that it was not a standard of quality. Category romance ( if I am not mistaken ).
If it’s not hard, listen …Thank you !

I think its too expressive for stock music. The usage is very limited.

I think the mastering is a bit too harsh, and the bass really sticks out to me.
The music itself I think is great but maybe the lead guitar is too front and centre. It’s not the kind of background solo guitar that I imagine people expect stock music to feature.
If the guitar had more space between the licks and it was a little further back in the mix I think AJ would let it in.

A track like this I’d save for an album of your own and make a watered down version for AJ. Good luck!

Thank you !
