"Take the Adele record, for example. It's an amazing record and everybody's so shocked that it's such a phenomenon. I'm not. You know why that record's huge? Because it's f**king good and it's real... Imagine if all records were that good. Do you think only one of them would sell? F**k no! All of them would. If all records were that good the music business would be on fire, but they're not." Foo Fighters star Dave Grohl joins the celebrity Adele fan club.
