Music, music videos text database possible to download …

Hi ,
I am new user of Kodi with big set of music videos. I tried both ‘mv’ scrapers. The second is mad and the result of it’s work is crazy and can not be used seriously , but gives big fun in the first hour of use it’s results.
The first (TheAudioDb) if works (it has to be rare occasion) returns very very limited results.
I am not able to understand why using in the name the chars ‘ ` – & , or not using it, prevents receiving correct result. I read, the only way is to create own .nfo files with data based on the name of music files .
It is easy for me , because I keep my set in one place on my NAS and use only links to files , which I am able to create in every way in every nameing convention (created special subdirectory for Kodi with ” – ” separator).
My files are labeled not only with using artist and title names but additional if band or singer, if singer – female or male , the type of music (but very limited set), file quality, music quality , adult info … but it is not enough or not all data are correct data (especial music type). I am sure I will find in the database better information (maybe except adult info).
I imagined the access to text version database about music (or music videos if exists). I will be able to find additional information from text records if I use artist and title from my music file (gawk,grep,…). If text database about music videos does not exist, it can be music database . The information about producter or film company is not very important.

Time for my question. Do you know about possible to download music text database ?

It has to use repeated internal structure , where fe. music type info will be at the same field possion in each record, possible to make a search for fields without parsing each record each time.
(I want to be precise, I do not need descriptions or links to pictures in the internet , only data : <title> , <artist> , <album>, <genre>, <year> all the rest will be a bonus )
