Inspired by this thread and this post in particular which mentions two songs called “Right Now”, how many other sets of songs can we think of that have the same title but otherwise nothing in common? For example, two of my favorite songs happen to be named “Send Me An Angel”, but one is by the Scorpions and the other by the Pet Shop Boys. Other than both vaguely fitting under the pop category, they really don’t resemble one another at all.

“9 to 5” by Dolly Parton and Sheena Easton. Both were released in 1980, so Easton’s was changed to “9 to 5 (Morning Train)” for the US release.
There was also a 2005 song by Lady Sovereign with the same title.
“Right Here, Right Now” - Jesus Jones and Cassandra Wilson. I just stumbled across the latter yesterday. And looking on iTunes, there are about 40 artists with songs titled the same. No way I’m listening to see which are covers.
IIRC
“The Power of Love” *Huey Lewis and the News, Jennifer Rush * and also Frankie goes to Hollywood were all different and all in the UK top 40 at the same time.
Oh, that reminds me…there was another song called Complicated doing pretty well at the same time Avril Levigne’s was…Carolyn Dawn Johnson, that’s who sang it.
“Walk Away” by Neil Young and James Gang and Black Sabbath
Three songs with the same name.
“Patches” by Clarence Carter and Dickie Lee
“Beautiful” by Gordon Lightfoot and Carole King
Wow! I never imagined there were so many…It seems the most popular titles are:
Quartets:
“Butterfly” by Crazy Town, Mariah Carey, Delta Goodrem, and Smile.dk
“I Need You” The Beatles, The Kinks, America, and Paul Carrack
“Someday” Glass Tiger, Mariah Carey, Sugar Ray, and Nickelback

“Lady” Styx, The Little River Band, Kenny Rogers, The Whispers, D’Angelo, and Lenny Kravitz
And the grand prize winner, a septet:
“Hold On” Ian Gomm, Kansas, Santana, En Vogue, Wilson Philips, Jamie Walters, and Good Charlotte
When you mention Andrew Lloyd Webbr’s “Hosanna” you have to verify whether you’re talking about Jesus Christ Superstar or Requiem.
I wonder how many other composers have written two songs with the same title.
“Somebody To Love” - same title, two different (and good) songs recorded by Jefferson Airplane and Queen.
Interestingly, “I Want You, I Need You, I Love You” was recorded by Elvis Presley. 
Octet, actually. Yes also had a song titled “Hold On” on 90125
You can add Tom Waits to the list.
Fairport Convention have recorded (though they did not write) two completely different songs called “The Deserter.”
About 12 years ago, three groups had more-or-less simultaneous hits all entintled “Creep.” Stone Temple Pilots, Radiohead, TLC.
Sheryl Crow and Mary Chapin Carpenter both have songs called “Come On, Come On.” One of them might be called “C’mon C’mon,” though.
