When you refer to a specific song...

[Combusken BG]

Always song name, then band/singer name.

[Jasujo]

I usually say Song Name by Band.

Same. That's how I usually say it both irl and online unless I say something like "Hey, have you heard <blah blah>'s new song?" lol

[Xerophyte]

<Band Name> - <Song Name>

Just seems logical to me.

[Tymaporer]

Usually I say "Song by Band."

If I'm being all conformist in a thread where people are posting about songs, I say "Song - Band".

I guess it's related to my hatred of the "author first, then title" system with books.

[draconis]

Online it's always The Song by Band Name; IRL it's usually Hey have you hear SONG? ..y'know, by BAND NAME HERE?
