What are the best 90s songs you can remember?

Please, I need some help setting up a 90s night with my friends. We'll have some dancing, karaoke and similar stuff and I'd like to hear some suggestions. Please, no country or rap. I want GOOD music, the nostalgic kind that rips your heart apart, e.g. I Don't Wanna Miss A Thing lol. Btw I like rock, grunge (Nirvana hello?), pop, techno, Latin, even Celine Dion (whatever genre she falls under).
