**Is your feature request related to a problem? Please describe.**
I notice that when playing a song in Youtube Music, the interface will show a year. When using get_library_songs. there doesn't seem to be a year at all.

**Describe the solution you'd like**
If the year can be scraped somehows from Youtube Music, I would like it returned for each song.

**Describe alternatives you've considered**
I am currently using Musicbrainz to find this information, but most of my 50s through 80s songs are missing from a generated playlist my script makes. I am not sure if most of the versions in my library are rerecordings and are not being matched back to the original, or what. If I can get the year directly from Youtube Music, it would narrow down my troubleshooting duties.
