Most of the time, I just use Google search to find a song when I know the lyrics (or part of the lyrics). Here are some useful tricks that I think will help you on the search for lyrics:
1. If you use quotation marks in a search on Google, it will only find instances of those words in that exact order.
When you don't use quotation marks, the words are sourced from different parts of the same document or page.
2. Lyric sites like Rap Genius are pretty good at hosting and helping people find lyrics.
Just try typing "lyrics finder" into Google and you'll come across many alternatives too.
