The website looks a bit outdated. The logo design and the background looks a bit old. Maybe there is a designer who can give you a more modern design.
The main title MP3 STORE is very generic and bad for SEO. You can try to use a more specific title to make it easier to find. Erotic MP3 Store I think will be good to start with a more specific title.
I will add a “free trial” just to understand how this is. It is a very niche product and I guess more users will not understand how this works.
The menu at the bottom looks very dark.
I will change the “read more” for “buy now”. This is an online store. You want to buy.
I will add the WhatsApp Widget just to help your customers buy faster.
