A song from the 1970s that you like or means something to you.

Lots to pick from here. I grew up listening to a lot of music from the 70s even though I was born in the early 80s. When my family went on roadtrips we'd all play "Name that Tune" for control of the radio. It'd be on my parents choice - Classic Rock - to start. We became very conversant in the music of Boston, Kansas, Chicago, Fleetwood Mac, Heart, and on and on. If I was going to pick one stand out track I've always loved Led Zeppelin. In particular, their track Over the Hills and Far Away has always been a jam of mine. It came out in 1973 (had to look it up to make sure it fit with in the bounds of the prompt) and is well worth a listen.
