you remember those punk rockers, rancid?
I do!  They were founded in the 80's, but I still remember the band!
are they good
Yes, they are great.  They have released nine albums to date.  Do you like punk rock?
It is okay, so would you say that all nine albums were successful?
Not so much for 9 albums, but they are credited for reviving mainstream interest in punk rock through the 90's.
do they have any popular songs?
Probably not many you would recognize.  Punk rock is a weird genre. 
why do you think it is so weird?
Punk rock is produced with short or fast-paced songs with hard-edged melodies and vocals. Very different kind of music.
