Sorry, Here's a case where the hint is longer than the solution (s'ok, reading is good for you)

Song / Artist
Four wds to describe the First step in how you and I sleep / Horace Greeley's 2 word advice to young men.

Wow, back to the 80s. I remember the song playing, but not the group/name:
We Close Our Eyes / Go West. Very weird video:

I had come up with Go West, amazingly, but couldn't get anywhere near a song. Probably because I quit listening to radio that played new music about 1984. I don't recall hearing this song.

"That was very interesting music Marty."

Mike Reno's group / Putting your effort towards Saturday and Sunday = [band/song]

Correct. Give us a new one.

Time Of The Season / The Zombies

Mythical river / Infant = [band/song]
