User tags and keywords for songs
To expand on the "performer category" suggestion...
A way for users to attach multiple user-tags or keywords to individual songs in their index would be very useful.
The tags for a song might be entered (and displayed) ONLY in the song editor, perhaps as a second (hidden) line in the title field.
(edit: even better, if the hidden info could be easily toggled to display, or not)
The tag/keyword line would not display on the chart in song view, but still might be searchable using the current song index (title) search field.
Without needing to maintain many separate playlists, a user could instantly, using the index search, bring-up all charts they've tagged as Sinatra, Cole, Como, Beatles, wedding, holiday, 1940's, a vocalist(s) or band(s) they perform with, or any other keyword(s) they chose to attach...
Currently, users append personal notes in the title which is quite cumbersome.
Thanks,
