The metadata is to a large extent clearly structured - there is an information about the artist, the title, the album and several more.

Nemp offers the possibility to add arbitrary, unstructured information to an audio file as well. This can be additional information about the title (e.g. "Singer-Songwriter", "Female vocalists"), or a list of alternative (sub-)genres (e.g. "Melodic Metal, Symphonic Metal"), or more personal additional information like "Holiday 2022". Nemp displays these extended tags in the file overview in the main window. 

If the quick access to the metadata is allowed, you can add a new tag by double-clicking on "[Add a Tag]". When you do this, the new tags are checked against the rules you can specify in the tag cloud editor, if applicable, and corrected if necessary. This will avoid different tags in slightly different spellings.

For the ordered presentation in the tree view or in the coverflow, these extended tags are not of any interest. However, when you use the tag cloud to browse the media library, these extended tags are included for building the tag cloud.

Tags from last.fm

Of course, it's a bit tedious to enter additional tags for every single title in the entire media library. But what is the Internet for, after all? On last.fm, there are not only covers, but also other tags that are maintained by the community - perhaps you have already tagged some songs yourself using them. Nemp can query the most common tags for a song from last.fm and save them in the media library. To do this, select the files you want to tag and choose →Get additional tags for selected files from the context menu.

Note: This only works if the files already have proper default ID3 tags like artist and title. And this takes some time. First, the internet is slow, and second, the admins at last.fm get angry if a program strains the API too much. About 2-3 files per second is ok, but not more. Nemp therefore deliberately slows down the requests.

With these additional tags the tag cloud becomes a bit more meaningful. Unfortunately, last.fm has many tags in different spellings, which creates a bit of disorder. A little remedy for this is the built-in tool tag cloud editor.
