Some busybodies have a lot of time on their hands!
I'd just ignore it, myself, but I'm not a musician or a lawyer, and so I'm not really in a position to comment as to whether it's right or wrong. I guess in the eyes of the law it'd be wrong if the lyrics are copyright, but really I'd imagine most musicians would be more concerned with illegal file sharing than reproduction of lyrics. I dunno. One way around it though is simply linking to the relevant page of a lyrics website or something like that. I'd probably click a link if I came across it and liked the photo.
I think there's an interesting subject related to it though. I've seen quite a lot of lyrics reprinted on PBase with photos somehow interpreting the song or certain aspects of the lyrics, or the mood etc. etc., and coincidentally was actually even considering doing something similar today for my PAD (it was gonna be Leonard Cohen's "Hey, That's No Way To Say Goodbye" and my PAD would have taken a plummet into sad, murky waters for 24 hours or so

). I've decided not to though, so there will no doubt be a far less interesting photo of a bin, or something.
Anyway. The reason for not doing it, and I think this is a far more important thing to consider than copyright issues - but that's just my personal opinion obv - is out of a more general respect to the writer of the song/the song itself. I guess it doesn't apply to all songs, but with a song like that Leonard Cohen one, the lyrics are so damn amazing it's almost an insult in my eyes to take a certain man's words about a certain girl at a certain time and try and apply it to me by way of photography, however apt it may seem today. It just seems really presumptuous. Then again, and here's where my thinking is all cloudy, it's a great thing to empathise with lyrics or feel they're somehow relevant to your life. It's one reason why Song A appeals over Song B. And if a song spurs you on to do something creative, then obviously that's a good thing.
But still, sometimes when I see it done I end up thinking 'gah...that's just in no way relevant to the song itself', which can be a bit annoying if you love the song!
I've actually only ever felt comfortable enough to do this once, as far as I can remember (
http://www.pbase.com/stuegan/two_hundred_words), and it was basically because the gallery title referenced the song, which is about the same subject and contained a couple of lines that seemed close to the bone. But I felt at the time like it would be too much to post the lyrics themselves right next to the photos. Looking at it now I wonder whether it's worth linking to them...ie does it improve the gallery in any way? Probably not. I'm not saying mine are, but if a photo is strong should it really need someone else's lyrics to help carry the message?
LOL Oh bloody hell I'm not sure whether I agree with it or not now ha ha. Anyone have any opinions on this?
