Identify and connect same songs

[rstemmer]

Identify and connect same songs.
Use-Case: There exists the same song in the music collection. Once in a Single Release, once in an Album.
There may be multiple connections for example when there exists multiple cover songs.

I remember a library that does fingerprinting songs to identify similar/same songs. I could use this.
The connection can be done by a new table in the music.db file with the following columns:

• Song ID A
• Song ID B
• Type ∈ {"Same", "Cover Song"}

Questions to clear before:

• What if the user accidentally connects two songs as "Same"? - The old Flags/Tags states need to be backed up.
• Should there be a visualization of this connection (Like a link? How to visualize multiple Connections?)
• For cover songs, how to highlight the original song?
• For multiple cover songs, should they be directly connected, or through their original song?

Tasks to do:

• Find the library to compare songs
• Add table into database
• Add an entry in the context menu of songs to allow adding connections
• Synchronize Flags, Tags and Likes/Dislikes for connections of type "Same"
