I'm feeling like listening to classic musics right now, so what are the best songs from the 60s, 70s and 80s in your opinion?

My personal picks:

70's Micheal Jackson
80's Bon Jovi, Whitney Houston, Madonna, Donna Summer, Tina Turner

Can't say the best song, I don't know it, but I do know ones I regard highly for a variety of reasons. There's a wide range of potential genres and bands that I could consider my favourite. I love New Wave, Synth Pop, Hip Hop, Punk, Post-Punk, alternative, shoe gaze & Dreampop, electronic, there's so much. Maybe I'll do genre specific posts in this thread. I have a few:

All of these songs are from 1979 in the UK.

Joy Division

Kate Bush

Sioxsie and the Banshees

Echo and the Bunnymen

And close it out with Gary Numan

Here are some other related songs from the 1980s:

Echo and the Bunnymen 1984

New Order (Joy Division after Ian Crutis's suicide) 1986

And I'll throw in some Tears for Fears have a lot of enduring hits, but this is my favourite from them 1982

And throw in some My Bloody Valentine (technically, they're from Ireland, but are primarily English band members) 1987

But speaking of Irish music, Thin Lizzy... 1977 - early photo-metal song

Something thrown together - there are many more I'm sure
