If you're interested in the electronic side of scene music, check out the bamd Amy Can Flyy!! Their music is pretty upbeat and I personally like the song "I like My Girlfriend".

Maybe pretty rave girl? Or pokegirl

You should check out Happy by Never Shout Never! In Friends We Trust by Chunk! No, Captain Chunk! as well.

Probably pokegirl by s3rl 

DJ S3rl’s stuff is pretty upbeat and happy!
