Most of my imagination centers around music so Id say mine are a mixture of :

The very bassy (deep sounding) and pounding echoing chords (more than one note being played at once) that seem like it will never end of "Beethovens (never could spell that dudes name! So the spelling may be wrong) 5th Symphony", And I welcome the however brief Whole, Half and Quarter note rest stops.

Then there the calm float through the air of the flowing melody of "The Music Box Dancer" and "The Entertainer". In which I seem to know its there but I can just float on though it instead of taking a pit stop on the Whole, Half and Quarter rest stops.
