My Question or Issue

recommended songs are set by taking the same word in the title of the playlist and songs instead of lookalike songs 

example:

title of playlist: bird of...

song in the list: something with bird

recommended: all songs with the **bleep**ing word bird.

i got the same with all my other playlists.

one is called: by the sea

i only get recommended songs with the word sea or searelated like sailor.. wth

someone who can help me out?

pretty please?
