I use the Now Playing Assistant very often (in fact it's the main thing I use to switch between tracks), and I only search songs by title. Unfortunately, there doesn't seem to be a feature to search only by title, if I search a song title it will also match the album's name.
By searching only by title, only the first two results should be shown, not the last one.
I guess that's a simple feature to implement as well (correct me if I'm wrong), this could be maybe a simple checkbox in the Now Playing Assistant or a setting.
Thanks in advance
