IMO,
context should always be explained. If the song is about a historical event, for example, or if there are references made, or if there is some backstory involving something that happened to the singer or band, then that kind of stuff should always be included or linked to. A number of lyrics I’ve posted have prompted me to do writeups on people and events mentioned in those songs.
Explanations of the song we can do without, I think. Most songs speak for themselves, and people don’t need to be told what it’s about. "In this song,
Madonna is explaining how her current love affair has such a transforming affect on her that she associates it with the powerful feelings of her first sexual experience and sheds her jaded cynicism for
blah blah blah…" Please.
Most people like hundreds of songs. If they have strong personal feelings about a particular song or they associate it with a personal event and they node about that, that’s great. But not every song is going to spark that kind of association. Most of the time, people just plain like a song, and that’s it. What’s wrong with that?
