I have the same problem, lyrics (show notes) never load.
I think this only happens to me when I download BOL directly onto my iPod Touch. I seem to remember it didn't happen when I downloaded it to iTunes and then synced. (Not 100% on this, since I rarely get it via the latter route.)
I touch to see the show notes on my iPod and I just see Loading Lyrics... and the spinning circle. It never goes away, but it used to work. This has been happening for a few weeks now and I didn't know if anyone else was having this problem.
