There is a song It might be by the Dave Matthews band it say something like often times im lazy ...?

Also there is another song that says " she ladadadadadada la dadadadada" I have no idea who or what the name of it is...Please help me!

I'm pretty sure you're thinking of Jack Johnson, not Dave Matthews. There's a Jack Johnson song called "Flake" where the chorus includes the lyrics "and often times we're lazy."

The other song is also by Jack Johnson, it's called "Bubble Toes". Both of these songs are on the album "Brushfire Fairytales".
