This extension was used for a magazine site in conjunction with a customized mod_article_news module.
The documentation is fairly clear, but for me could use some better translation to my native language of English. Not a problem if you read carefully though.
It works everywhere - in content, modules, modules within modules, and tabs within tabs.
JU Tabs a great templating system for different stylings.
As a developer I will certainly look to Vinh's extensions whenever applicable.
Templating is improved by taking advantage of Joomla 2.5's override methods.
I always end up paying less for any add-ons I need to go with it than with other carts.
On top of all that, I get great support from the development team.
Support for this component is good as well. However -
The language file does not allow exclamation marks (!).
The removal of jobs leaves entries in your database that can show up in the frontend (duplicates).
1. Super easy to install.
2. With some custom code, multiple user types can upload songs from the front end.
3. Has some good styles built-in with many options for custom styling.
4. Loads songs from multiple directories, easy to have different media source directories.
5. Good documentation.
6. Excellent Customer Support. I got all my questions answered within several minutes of hitting "send" :)
7. I would pay $60 for this if developed as a Jomsocial extension.
