Another excellent song to add to this good list is "My Love" by Petula Clark if you have already taught comparatives and superlatives.  Also, to see if they can get the humor, what about the songs by Flight of the Conchords?  They have hilarious songs and videos are funny to - it might be a little too adult-themed though.

Excellent lesson, worked like a charm to fill in an extra class. The kids loved it - I've never seen some of them listen that hard! I'll be recommending it to all my friends teaching at high school.

Couple of changes I made to make life easier on myself:
At the start of the lesson I stuck a postit note in the centre of each desk, said if they behaved we'd use it for a game. Confusing enough to keep them interested. Once we started the listening game, the postit was what they slapped and where they kept track of their points, then at the end they wrote the winner's name on it so I could see who to give a prize to.

Instead of choosing a different phrase in each of the songs, I used their titles, for example in 'Call Me Maybe' they were listening for the words 'Call Me Maybe'. The songs I used (got through about 10 in a class I think) were:
Call Me Maybe - Carly Rae Jepson
Beautiful - Eminem
We Are Young - Fun
Somebody That I Used To Know - Glee version
Better Days - Goo Goo Dolls
Cry Me A River - Justin Timberlake
Plug In Baby - Muse
I'm Not Okay - My Chemical Romance
Little Things - One Direction
Fireflies - Owl City
Hey There Delilah - Plain White Ts
By The Way - Red Hot Chili Peppers
On The Radio - Regina Spektor
Umbrella - Rihanna
Love Story - Taylor Swift
Titanium - Madilyn Bailey acoustic version
A Thousand Miles - Vanessa Carlton

I was trying to get a mix of genres while keeping all lyrics and videos school-appropriate. Took me ages to check through all the videos so hopefully this will save someone somewhere some time, though you may not feel the We Are Young/Umbrella/Plug In Baby videos are appropriate for younger students so check those out yourself. I downloaded all the videos using keepvid.com, which is a fantastic tool.

For the first gapfill, I used it as it is here, but I think it might work better with songs where the chorus is repeated - Yellow in particular they didn't catch first time through, so I had to keep rewinding. It's nice if they just have to wait for it to come round again.

Two thumbs up - fun and easy to set up, kids loved it, and it felt worthwhile :)

You have obviously put a lot of work into this, thank you so much, excellent material here.

thank you so much

THANK YOU!!

I used Katy Perry's "Firework" to help the students practice listening. On the first part, I provided 2 words and they had to choose the correct word. On the second part, I added extra words to the chorus and they had to scratch out the words that weren't in the song.
If you choose to use youtube.com, I recommend not showing them the video  (I can cover up the TV screen in my classroom) so the students can concentrate on listening.
Then I played the OP's slap game but I didn't use the music cards. I just had them stand on either side of a desk in front of the screen and be the first to slap it when they heard the lyrics indicated on the screen.

I used grooveshark.com to make and save the playlist ahead of time.
This lesson went over pretty well with even my usually lethargic 3rd graders.

  Well everything, including the worksheets, is in PowerPoint. How do I convert the PowerPoint music cards into a format that can be printed off and handed to the students?

How do u download ppt files? I can't download them.
