Searching things on foobar2000 seems needlessly complicated.
On Spotify, I can go to my favorite songs, type in a keyword (band name, song title) and it filters the whole playlist to show only that. Then I hit play.
On foobar2000, if I try to do that, it *blanks my whole playlist* and shows no results, forcing me to reupload my entire 1200+ song playlist back into the playlist manager so I have songs again.
Either I have foobar configured wrong or I don't have the right plugin installed.
...I just realized that I'm probably using the wrong search feature as I found out there's a Playlist search in the main options.
Still frustrating, though.
