I am doing a research about this problem for a school project. I, personally get pissed off because of the searching system of spotify... But my opinion is not enough for the project, please answer!
Your opinion is not enough because you would only be exposing your lack of research. There are thousands of sites that exist to catalog lyrics and make them available to anybody who knows how to search for them. If you want to use the internet, you HAVE to know how to search. The easiest and best service is google.com - just type lyrics "bibbity bobbity boo" and up comes "Cindarella", links, flicks, maybe even sheet music (not usually sheet music). While you are at google.com also search "google advanced". Learn this stuff. This is like knowing how to count.
