Allow Users to Manually Edit/Rename Track and Album Titles in Their Own Library

[hyne]

I would like to request a feature that allows users to manually edit track titles, album names, and artist names within their personal library.

Just like the "Get Info" feature on other platforms, a user should be able to right-click a song or tap a menu to rename it. Crucially, these changes would be strictly local—the edits only apply to the user's personal account and library, leaving the global metadata untouched for everyone else.

This is a massive quality-of-life feature, especially for international music fans. When albums are uploaded entirely in non-Latin scripts (like Japanese Kanji/Kana), it makes navigating the library incredibly difficult. Allowing us to personally rename or romanize our saved tracks would solve this completely. It also helps fix messy metadata, typos, or inconsistent album formatting without affecting Spotify's global database.
