Your joking right? I hear you are just one of those Alternative/Indie cool kids who think that if alot of people like a band, you shouldn't.
Wow. Someone else knows the Triffids, gun. I only know them because Robert McComb was my teacher and house leader though.
Back in Black has sold over 49 million copies worldwide, fmd that is pretty impressive. Best selling album by a band, second to Thriller by Michael Jackson in terms of albums overall.
The fact the backstreet boys have one of the highest selling albums proves that sales aren't everything when it comes to music talent.
