"Don't look back in anger" by Oasis is disturbingly similar to John Lennon's "Imagine". In fact, before the Don't look back drums kick in, I thought it's Imagine.
That's a bit like writing a song and calling it "Stairway to Heaven". It's not illegal or anything, but...
I haven't heard a lot of Oasis songs, but if that's how they do their thing, then no wonder Raskolnikov's posts sound like his avatar!!
