HELP! tuning...

[Jonesiani]

Hi all, i've been trying to plat Blackhole Sun, by Soundgarden. Now every tab i've read, says it's in drop-d tuning. I really don't think it sounfs right? I've tried drop E Flat and that does'nt sound right either.

Now i'm just plain confused. Can anyone help me out???

Thanks!

Thanks for the replies so far.
I can play the song in drop D, it's just when i play along with the origional track, i swear it sounds like the origional has been tuned up.

Oh well.
