I understood it this way:Sirius died because of falling through the veil.If this helps you,try to imagine Sirius evading a shot,but finding an electrified wall.Anyway,I lost interest in the story after being infused with the hormones of half Hogwarts alumni.I haven´t read the last book and I won´t read it until some acquintance wants to lend it to me.I want to see what happens in "the final battle"...well,I know what happens,but still...

I like Coldplay,but I can´t be arsed to listen to their last album again,even though I´ve only listened to it,and it was track-by-track.

Nickelback?They finished their career with "All the Wrong Reasons".At least for me.

Audioslave was a different case:I liked them a lot,had a poster of them in my room,and "What You Are"still means a lot to me,but I barely listened to anything which wasn´t on their first album.I can´t say I cried when they split up

I like rap.I always have,but only if they have good background music and meaningful lyrics,like...RATM you say? I´ll try to listen to them.

You can find good rap music out there,such as MadLib or Sage Francis.
