Amazing! Something I've been meaning to build myself and now I don't have to. I'd like to echo the need for multiple song search—my use case for this was good playlists in cafes where I want to identify the playlist based on 1-3 shazam'd songs.
not a password rule but: i use a password length of > 40 characters because why not? signing up for paypal worked with that no problemo until i had to sign in again and the login input ignored everything north of 20 characters or so. It worked after removing the maxlength attribute :(
