Yeah, it's a great song. It's surely somewhere in the top 10 of my favorite Cranberries songs. "Dreams" and "Linger" from their debut album were bigger hits in the US but I feel that "Zombie" is their so-called signature song and "probably" the first song that most people associate the band with. I just want to note that their final album (released the year after Dolores' death) was a fine finale, if sobering for the fact that it really was over after 25 years. It's definitely worth a listen.
