In general,
the individual who writes or records an original song owns the copyright in the musical work or sound recording. So if only one person is involved in the writing and recording process, then that person owns the resulting copyrights.
even bns had a similar case few years back for copyright issues with rohana weerasinghe.. .. its a crime to steal other peoples work.. lankawe owa karata .. what yohani did was a cover and its not her song..it sangeeths song..so he used differnt artists..
what iraj said was its ok to do covers ,sing onstage.. but uploading to spotify or deezer .. onna thats over the limit..
hithapan umbala mahansiyen..ra nidi waragena.. sinduwak hadanawa.. ..eeta passe kohey hari podi ekek ey sinduwa cover karala..eken hamba karnawa..spotify danawa.. ..umbe hama ..eth kohewath inna un salli hoyanne.. adu tharamey umben awasara aran kara nam kamak nah..
Bandu samarasnghe and BIndu.. oya thiyene ey wage nadu..

i dnt think in future no one will let that women do cover songs..
