What should be Riz's theme song???

Ok, so there are these things called theme songs. I want to know...what should be Riz's? (I dont have apic on this computer, so just go to the Invader Zim Roleplaying club, and cari thru peminat art-you should find RIZ) Okies...now, Riz's perosnality-she's very tough and stands up for herself, she can be a bit serious in serious situations, she can be crazy, and she can be nice. Just depends on her mood. XD She loves her extremely stupid robot Cheese, but she can also be simply FURIOUS with her too. She is really good with new people and she loves making new fwendz. SO WHATS HER THEME SONG? IM LETTING anda DECIDE!!! When anda answer, plz include the name of the song, the artist, and if anda could please, give me a link to the video (if there is one) on youtube.
