From late 2008 to about, oh, 2011 or so I was pretty obsessed with Alanis Morissette.
I can't say why I became obsessed with her, exactly, but it was pretty much kicked off when I heard her very first album almost back-to-back with her third, more popular album; the juxtaposition of silly teen pop with angry alternative rock must have intrigued me enough to want to hear how her musical evolution unfolded.
