that's just a spin.. you should still pay for the music initially...
It's true, many bands are adapting... Radiohead released their last album digitally and let people choose their own price for the album... allegedly they made more off that album than any other. You're diverting from the REAL issue though.... people are still stealing the music. Live shows have ALWAYS been a major source of income for bands. NIN/Radiohead were already rich.
I don;t think there are many live shows worth paying 80$ for.... Gwar is worth seeing live, but they were only 20$ when they came here.
