The Welsh Government says it'll change Welsh planning policy to provide more support for live music venues.
Environment and Rural Affairs Secretary Lesley Griffiths says this will include the 'Agent of Change' principle, something campaigners have called for.
This means that if a new development is proposed near an existing business, like a live music venue, then it will become the developer's responsibility to mitigate potential noise problems.
A similar change was made in England in 2016.
The proposal will also allow the designation of "areas of cultural significance" for music within Local Development Plans.
It follows the popular Save Womanby Street campaign, which highlighted the plight of a number of venues in Cardiff.
