Oh god, I do it all the time.
I've been latched on to Black Veil Brides "Rebel Love Song" for the past week and a half:

Before that, it was Avenged Sevenfold "Welcome to the Family" (also for about 2 weeks):

Oh, and just to fit in with the common theme here... I had a really bad Lady Gaga fetish that started with "Judas" on Mother's Day, drifted into a dance remix of "Telephone" ~2 weeks later, and peaked with "Blaze of Glory" right after the 4th of July. Then I got kind of burned out on Lady Gaga, and drifted back into metal.
Going back further, I latched on to Rise Against "Life Less Frightening" really, really hard about a year ago. This one lasted for almost a month:
