song suggestions for an 8 year old's playlist

[notnowmaybelater]

Dc3 is 8 and has his first MP3 player. He's thrilled but listening to the same 5 songs over and over:

Life is fun
Don't mine at night
I am a Gummi Bear

And two German songs from silly but age appropriate YouTubers...

If your 8 year old likes this kind of nonsense what else do they like? He's rejected his older sibling's recommendations as boring, so I said I'd ask MN...

Ds is 7.5 and has just made his first playlist. He also likes silly songs. His favourites are:
Everything is Awesome
The Catchy Song
Ghostbusters
Tubthumping
Bohemian Rhapsody
Matchstalk Men and Matchstalk Cats & Dogs

...and, er, Material Girl.
