If further evidence were needed that digital music files of one form or another are taking over the world, we just received a review CD called Acoustic Love Songs. Inside the CD cover was an insert providing instructions on how to download the songs as mobile ringtones from Vodafone Live. Clever cross-selling, I guess. What's not so clever is that you'll pay Vodafone's standard $3.50 (polyphonic ringtone) or $4.50 (real tone) for the privilege of hearing James Blunt's lupine howl every time someone calls you. Great.
