I use Music Collection since 1 year now and I can confirm that it meets my needs perfectly!
The amount of modules and plugins and their configuration flexibility (features + css) offer a real advantage for customizing your music site to fit your needs.
In addition to having a high quality product, you can count on a 5 stars support service. The architect behind this extension also offers a customization service that makes customization options unlimited.
Thanks Germi for that great extension!
