I haven't got a chance of winning so whoever wins and is stuck on a theme. Feel free to steal one of these ones I've thought of:
All about that Bass - songs with a prominent bassline
Foul mouth - songs which drop the f bomb
Creativity - songs containing artistic elements in the title. Drama, music, paint, colours, etc.
long song redux - just so dream theater has a chance of winning.
Please no Katy perry - songs with hot, cold, warm, etc in the title
Here comes a bear - over, under, around and through in the title
What's my line? - songs with la, do, humming, whistling or any other ad libbing
Just for
Gigantor - a Capella featuring a drinking receptacle.
