I would’t worry about it to much. Envato has always just copy pasted that response for almost anything, any reason. Maybe they found it to similar to another track? Or most likely they are just looking to accept salsa tracks right now to fill a missing gap in their catalog. Or maybe the reviewer is just having a bad day at work… I’ve had really stupid, useless tracks accepted with no problem, and also some great ones rejected. Including one, the exact same track I still own that has been used and licensed to over 60 trailers worldwide. Exact same track. lol
Gota remember These sites are run by failed musicians. Failed as in, they didn’t make it with their own music so their job is now reviewing yours for submissions. So even tho there are some solid business people there, they only know what’s been sold before. They don’t know what will be sold tomorrow…
Your track sounds awesome by the way! It’s exactly what stock media sites need. Quick, cheap and works well to bring that feeling across. It doesn’t hurt to try other sites, we all sell across hundreds of these sites.
