Hi !

First of all, thanks a lot for all that tremendous work (๑′ᴗ‵๑)

1. I have a huge library (as all of us I guess ^^), common albums, not very popular albums, soundtrack albums or compilation albums (various artists) I wan’t to reorganize thanks to beets, some of the albums are going in my genre folder as I wanted, but some of them are going in a `_` (underscore) folder, I can’t understand why.
2. As I’m actually testing (and messing a lot) with a test folder library before using beets with its perfect configuration, is there any way to « reset » or clear library.db ?
3. Sometimes there are artists duplicates, I mean real ones with same band name, how do you guys manage that so you get the good one with its right genre ?
4. Sometimes, there is no genre in musicbrainz artist page, is there any way to put these album forlders in a special folder that tells me to manually manage it ?

```auto
beet --version
beets version 1.4.9
Python version 3.9.2
plugins: bpd, fetchart, lastgenre, lyrics

```

Thanksss to anyone reading this ◎ヽ(^･ω･^=)~

> some of them are going in a `_` (underscore) folder, I can’t understand why.

Check the FAQ and maybe your replace config. My guess is the genre is not ASCII-compliant (ASCII = anything on a keyboard, basically), and so it gets renamed to \_.

Just delete the file, if I understand correctly. Move it somewhere safe if you aren’t sure.

As in, two unrelated artists of the same name? You want to distinguish Michael Jackson the pop singer from Michael Jackson the [didgeridoo player](https://musicbrainz.org/artist/ce8f1c65-1c0e-4685-bea5-f7a27a20b3bf)?

This is a last.fm problem. AFAIK they do not have any dedupe on their end for artists. See the page for Love for example: [https://www.last.fm/music/Love/+wiki](https://www.last.fm/music/Love/+wiki)

Found by searching ‘lastgenre beet’:

[https://beets.readthedocs.io/en/stable/plugins/lastgenre.html](https://beets.readthedocs.io/en/stable/plugins/lastgenre.html)

Are you sure it’s going to _musicbrainz_ and not _last.fm_?

> **fallback** : A string if to use a fallback genre when no genre is found. You can use the empty string `''` to reset the genre. Default: None.
