TorrentFreak: How To Kill The Music Industry:

According to Per Sundin, CEO of Universal Music, the decline in music revenues in the past 8 years can be fully attributed to (read: blamed on) illegal file sharing. If this were actually true, many of us might even respect his decision to go after pirates as fiercely as the music industry is doing right now. However, the past 8 years have seen a lot more changes in the landscape of home entertainment than Per Sundin would like to admit, and some of those changes have had a massive impact on music profitability — much more so than any amount of piracy.
