I almost always apply a little EQ to most things, to apply a little colour, or to place things in the mix. I mix libraries and have to use EQ to make them fit together a bit better.
benskia saidCheck out classic FM for example, and how much you have to turn up the volume to reach a level comparable with other radio stations, due to the lack of limiting and compression.
Classic FM highly compresses and EQ’s its playback. Compare it to BBC Radio 3, and you’ll hear the difference. Classic FM boosts the Bass substantially and highly compresses it which is why it is significantly louder than BBC Radio 3.
Besides, it depends on the style of music you’re writing. More classical stuff will require less EQ than say, Epic Trailer music.
