Should you build this?

YES, if

You can ship in 1-2 weeks on $0-20/mo infrastructure

THINK TWICE

10 competitors already shipping — crowded, harder to differentiate
Only 2 mentions across platforms — evidence thin, validate before building

VALIDATE THIS WEEK

This weekend: DM users at reddit:digitalaudioplayer (2 complaints · top ↑116) — ask if they'd pay $9/mo for a fix
Next 7 days: ship a 2-page landing site with $9/mo waitlist + "request beta" form — count signups
If <10 signups in 7 days: kill it · the demand isn't there at this price
