Since Petula Clark was mentioned above, if someone mentions “Downtown” her song would still be the version that I think of. I wonder if most people wouldn’t think Macklemore these days. And to be honest, I like his “Downtown” song a lot more.
One of the most diabolical examples has to be Robin S’s “Show Me Love” vs. Robyn’s “Show Me Love”. Both were hits in the 1990s. Fortunately, my survival does not depend on distinguishing the two.
When I Google the song title “Rhythm of Love,” the top hits are not for either the 1987 Yes song or the 1988 Scorpions song, but a 2010 song by someone called Plain White T’s. Wiki tells me that there are at least nine different charting songs (or songs from charting albums) with this title, but the Yes one came first.
There’s a gazillion songs entitled “Hold On”; Wilson Phillips is of course the most popular, but I’m more likely to think of Santana, Kansas, Triumph, or 70’s one-hit wonder Ian Gomm.
“Learning to Fly”: Emerson, Lake & Powell is what comes to mind, even though Pink Floyd & Tom Petty’s songs were much more popular.
“Over the Hills and Far Away”: There was a time when I’d answer Led Zeppelin (like most people, I’d presume) but nowadays it’s more likely to be the Gary Moore/Nightwish song.
I was a top-40 listening 3rd grader when the Rod Stewart song came out. So I was more familiar with that than the Dylan song. Becoming more familiar with the Dylan song later in life, I don’t think they seem similar at all except for the name.
Also, I’m surprised Rod Stewart wrote the song. I figured it was a cover. His later career seems to be mostly covers, and even back then he was doing cover songs (Try a Little Tenderness, Downtown Train) and songs written by others for him to sing (My Heart Can’t Tell You No). His next album was all covers and a couple new throwback sounding songs not written by him.
Interestingly, searching you tube for the Led Zeppelin song caused me to find the Nightwish version, and I was quite surprised at how much I actually liked it despite never really hearing anything like it before. Then a few months later an Epica song came onto my normally classic rock station, and from there I got swept into symphonic metal and didn’t really look back (although I’ve gone on to a lot of different music since then).
