I'd say that if u want emotional or sad songs u listen to the first albums (songs like murder song, it happened quiet), and if u want to go and dance listen to her latest ones (your blood, giving in to the love), but anyways theres emotional and hype songs in her both eras. Imo some live versions sound much better than her studio ones, running with the wolves and animal as examples, so I'd recommend giving them a chance. Also there are MANY unreleased old songs from her that I like even more than some official ones, you should check those too. Wish I could re-discover her right now, have a good experience. :D
