Rejected tracks

Help me please, brothers and sisters. I just uploaded my last two tracks, that i know are not great but i think are enough good to be sold at least for one dollar. Why they are rejected? How can i improve quality? I use FL Studio 10. Thank you for understanding.

Don't upload products that you believe are not great and only worth a dollar. It wastes your time, Pond5 time and buyers time. It cost P5 a lot more to curate, store and sell than they are worth. Upload only products that you feel are valuable across many different uses. Music is and will get more difficult. There are millions of similar sounds.

Try to change the genre of your music

if you are investing a lot of time trying to make a track and sell it for $1 you are wasting your time. Learn the software and make great music and sell it for what it is worth.

Thank you. I have more work and may be try new genres.
