This track is not like Live Forever by Oasis. L.F. is an up-beat, happy-about-life track. M.W. is a vengeful track critisizing journalists. They are not like alike. I believe "Related Tracks" works in a way that means if someone listens to one song by an artist, and another track by another artist, then Lastfm assumes they are alike. We all now life is not as black and white as that, but clearly Lastfm as not devised a better way to link related tracks to each other. Not surprising really, as assumedly it would be quite hard to do so. Please feel free to correct me on this if I am wrong.
