Lyrical masterpiece

I have this annoying habit of constantly singing song lyrics over and over and over again, except that i don't actually know the song i only know say...2 words...but i will sing them whether i realize i'm doing it or not. For example awhile ago i had the song i'm bossy in my head...but the only words that i knew were...i'm bossy...so i sang them, and my roommate joy had actually never heard the song but she knew those two words. Which leads me to another song that i have gotten stuck in my head...one that as i like to call is a lyrical masterpiece. I don't even know what the song is about, i don't even know if i want to know what the song is about, but it is so catchy that i fell asleep to it in my head last night. and the only parts of the song i know are...umbrella ella ella eh eh eh under my umbrella ella ella eh eh eh eh eh eh. the other day my boyfriend and i were driving and this song came on and for some reason like my genetic defect of a brain clicked and i had to sing the words i knew...and then i kept singing them, and i've been singing them ever since. Call me crazy...oh wait i already am...but if this isn't some lyrical masterpiece that sticks in your head then it's gotta be some sort of political propaganda cause it's just way too catchy....
