I like a lot of the songs from the mid and late 2000's.
A personal favorite of mine is Dirty Little Secret by The All-American Rejects.
The Story of Evil songs are a little old, they're from 2008. I like those too. I learned how to play them on the piano by ear. Or at least the main three.
Well there's two Fly and When its Over both by Sugar Ray(google it if you have no clue who they are)anywho there my fave songs i listen to them every day(when i get a chance)
I don't know what song it is but this is one of it's lines
"All this day, I promise forever..All this day, I surrender my heart" that is very old but I like it since my friends and I make fun of it.
I also make fun of the song "Against all odds"
Here's my list: (random order)
1. Time After Time - Cyndi Lauper (1983)
2. Ain't No Mountain High Enough - Marvin Gaye and Tammi Terrell (1967)
3. Baby One More Time - Britney Spears (1999)

10. Everytime We Touch - Cascada (2006)
And anything from Michael Jackson (i didn't added because there will be lots) and "Barbie Girl" never gets old anyway and lastly i would say the EPIC Pokémon Theme!! =D
