Most annoying song, period.

The Birdie Song by The Tweets was pretty irritating but there is rather a lot of competition.
John Cage's 4 minutes 33 seconds is annoying by its very existance.

Bobby McFerrin - "Don't Worry, Be Happy"
I like it.  EVERYONE I've played it for has stuck their finger in their throat and made the "I'm gagging" face.

Paul Anka - Having My Baby.

My brother in law, back in 1979... as a projectionist at a theater... played that over and over and over, for the opening of every showing of ’Alien’.

No one in the audience knew why, at first...but they soon found out.

Higher Love by Steve Winwood.

I changed that one to "Bring me a rye and coke"....."think about it...there must be rye and coke"

My Sharona-The Knack

Cheech Marin redid that song

And to the op, the Foo Fighters rickrolled some +30k people. With Rick’s personal help...

That such fun can be had in this world...

... I discovered he was actually singing "Bird, bird, bird, bird is the word".

Hi Tim,

Thanks for your comment about "Surfin’ Bird," and for the link. The lyric is actually "bird is a word," at least in most places in the song, which I think is even funnier than if it were "the word."

Perhaps that lyric was inspired by a dance known as "The Chicken," which originated in the 1950s, and which the performer appears like he might be doing in the latter part of the video you and Geoff linked to. (The video, btw, is incorrectly titled "Surfin Bird - Bird is the Word"; just Google "Surfin’ Bird lyrics" for additional confirmation of that).

Best regards,
-- Al

You've lost that lovin' feelin'

Yes Yes I have especially for that song.
