Query: Midnight Oil has U2-itis

That is to say, when Oil, like U2, were at their prime, they made some of the most exciting, beautiful, and meaningful guitars-keyboards-drum-vocal rock ever. And lately, also like the boys from Ireland, they've felt the need to experiment more and more with their musical sound, adding all sorts of synthesized or otherwise unnatural elements and thus destroying the essence of the sound that made Diesel and Dust one of the greatest albums of the 80s. The lyrics are still driven by real and aptly-put political and social concerns, but without good, interesting, and enjoyable music to back those lyrics up, it just ain't the same. I hope that both Oil and U2 return to their more acoustic roots very soon.
