One thing that the ESV blog noted this week was that more copies of lengthy unabridged audiobooks are being sold.
I suppose that I'm a bit of an audiobook / lecture junky. When my brother was over he grabbed my iPod and started scrolling around on it looking for a song. Interestingly my iPod is full of stuff, but there's not a single song on it. (Talk about being nerdy!)
For those interested in grabbing a copy of the Bible in audio format, Chapters has the ESV Listener's Bible (MP3-CD edition) for about $39. For those willing to put up with a little DRM, Audible will allow you to get your hands on a version even cheaper (and get your hands on some other audiobooks as well).
My suggestion to you if you go for one of these is to be wary of the dramatized versions. I have a copy of Zondervan's dramatized recording of the NIV (from Audible), and they put in some fairly soft background music. The problem there is that the background music seemed quite repetitive and got rather annoying after a while. I do still like having a different reader for each voice though.
