help please installing

OK first I estup and enabled the bandcamp/soundcloud & mixcloud content plugins.
You can now use these services soundclips pages urls in your Joomla content articles and have the url automatically replaced by their respective players.

You might want to have a look at their settings to customize players look and features.
Open your Joomla backend, go to EXTENSIONS then PLUGINS management.
Search for Bandcamp and find the plugin.
The plugin settings have varous tabs: Bandcamp, Soundcloud & Mixcloud.
Have a look.

For the EasySocial plugin, there is not much to set , this is rather straight forward.
I tested with another user and it worked out of the box.
My suspiction about the reason it says empty playlist, is because it lodas the user playlist, and not other playlists. SO if you create a playlist, it won't load it. Try with a single or more tracks, but no additional playlist.

Hope it helps,
Let me know

please clarify "Try with a single or more tracks, but no additional playlist"
also so with bandcamp/soundcloud any user on my joomla website can click on menu linked to these modules and play music from these players?

- In your soundcloud account, add at least one track outside a playlist.
- The plugin changes soundcloud / mixcl. / bancmp URL for their respective player inside Joomla articles or everywhere content plugins are prepared. This is not a module.
