Foo Fighters mainman Dave Grohl has heaped praise on British songstress Adele - and reckons if every album was as good as her chartbusting '21', the music industry would be in much better shape.

Speaking to Billboard, the multi-talented musician opened up the current state of the music industry, believing that there just isn't enough consistent quality out there at the moment.

And he used Adele's hugely popular '21' as a benchmark as to how to write a great album. He said:

"Someone asked me recently, 'What do you think the problem with the music industry is?' I said, 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***ing good and it's real. Now imagine if all records were that good. Do you think only one of them would sell? F*** no! All of them would. If all records were that good the music business would be on fire, but they're not."
