Explore by …¶
Explore screen¶
The explore screen is devided into two sections: the SOM display on the left and the query result list on the right side.
Query results list¶
The menus on the top of the song list on the right enable to change between different collections (middle menu), extract subcollections by regions (left menu), or choose a selection (see below).
When searching for an item in the collection with the search text field on the top right, all songs containing the search term in the metadata are displayed. Below is an example of the term ‘Kachin’ searched for in ‘Collection Bader’. The word Kachin does not appear in all song metadata displayed. This is because on this screen, only the most important metadata are shown:

A list will open, which displays your selection. Click on a selection name to add the current song to it. You can also create a new selection from the same menu.
