I've come across a few too, in the past years:
- Intro of "Something to believe in" vs "Don't you forget about me" by Simple Minds
- verse of "All I want is everything" vs "Sign of the times" by Prince
- "Joey" vs "Levon" by Elton John
- Chorus "Tokyo Road" vs chorus "Let me entertain you" by Robbie Williams

There's even Bon Jovi songs which sound alike:
- All about loving you - Never say goodbye
- Bounce - One wild night
