試してないけど、こんな感じでできそう。
void remove_karaoke_tracks() {
　　search_filter::ptr filter = static_api_ptr_t<search_filter_manager>()->create(
　　　　"(NOT title HAS \"off vocal\") AND (NOT title HAS \"instrumental\") AND (NOT title HAS \"with out\") AND (NOT title HAS \"カラオケ\")");
　　metadb_handle_ptr_list tracks;
　　static_api_ptr_t<library_manager>()->get_all_items(tracks);
　　pfc::array_staticsize_t<bool> result(tracks.get_count());
　　filter->test_multi(tracks, result.get_ptr());
　　tracks.remove_mask(bit_array_table_t(result.get_ptr(), result.get_size()));
　　static_api_ptr_t<library_manager>()->remove_items(tracks);
}
