Miley Cyrus Vs Ashlee Simpson

They sound hauntingly almost the same, perhaps Miley winning by just a lil' bit with a better voice, but it really took me a while to figure out who sang that song 'See You Again". All this while I thought it was Ashlee Simpson's song since the radio deejays never make it a point to announce the name of song and singer like they used to. And then I heard Ashlee's "Pieces of Me" and gosh, they sound almost alike. But Miley is a bigger star - it's like Britney all over again, only I do think Miley/Ashlee/Stacci Oricco/Jojo well, they all sound the same to me.
