text: Utilizin' gravitational-wave (GW) lensin'
  New way to peep small-scale structure, no question
  LIGO, despite its coarse resolution and quick viewin'
  Detects GW lensin' from compact dark matter, no snoozin'
  
  Primordial black holes or compact DM, they got the vibes
  10-10^{5}  M_{⊙}, they're the ones we wanna find
  Lensing seen through GW frequency chirpin'
  Patterns change naturally, lensin' got 'em swirlin'
  
  Amplification and modulation, frequency-dependent game
  LIGO, the highest-frequency GW lab, puttin' it to shame
  Probin' light compact DM, they got the skills
  Advanced LIGO, design sensitivity, fulfillin' the thrills
  
  Three detectors, one-year observation, that's the plan
  Optimistic vibes, constrainin' f_{DM} to a few percent, man
