Changing thread titles is a time-honoured tradition in the Music section of the forum, and I have never heard of anyone complaining about it. It happens because people, mainly newcomers who don't know any better, often start threads like—

Help! I'm looking for song.
or
looking for song
or
Lyr Req: Need a Song
or
want to find a song

to name a few examples that we haven't got around to changing yet—but I fully intend to do it, as time permits.

The people who start this kind of music thread haven't a clue what kind of information they should put in a thread title, or why it matters. But they ALL—without exception that I know of—understand once it is explained to them, and then they often apologise for their ignorance and thank us for helping them. People who start BS threads are different.

My philosophy is that we're not just answering questions here. We're building the world's largest database of useful information about folk music (loosely defined), including lyrics, tunes, information about recordings, links to other useful sites, etc. Information posted here is not only for the benefit of the people who ask for it, but for unknown hundreds or thousands of people who might search for that information in the future. Therefore, the information needs to be organised in a way that makes it easy to find.

One of the ways people find information is by filtering thread titles, so it's important for thread titles to contain a full song title, or at least some important key words about whatever the topic is. I have probably changed hundreds of titles of music threads, and no one ever complained.

I once naively assumed the authors would appreciate it if I occasionally changed a BS thread title as well, but I learned better. Now I never change BS threads, and haven't for a long time.

Not that I think there would be anything wrong with changing them. I just can't be bothered to do it, given that it is a thankless task.
