There have been few earlier components each with functionality of setting up Music store, other with juke box, other being native to Joomla 1.5 and much others offering different features.

But wait, what is Zina?
It has offered everything in a single Joomla 1.5 Native component!
I hope it continues its development, because I fear there is none replaceable to this currently.

This component still being in beta stage, is excellent. One of the best feature I liked was the Built-in Bug Report tool.

Overall there are many great things which you can only know after using it.

Thanks for the component.
Hope new features in future!
