Metallica changed twice. Musically the band has not changed
Green Day is awsome. They can as good songs as Linkin Park. But I got to say something. Linkin Park changed in 207 when they released their album Minutes to Midnight. Linkin Park was difrent when writing hybrid Theory or Meteora. just because they changed dosent mean they suck. Green Day also changed and became better than they were before. Green Day and Linkin Park are my two fav bands and I like their songs. If you dont like these two bands, what do u listen to?
