Why are music albums by Malaysian singers NOT selling well in Malaysia now? What happened?

the reasons that Malaysian singers NOT selling well in their own country because we had listened to so many foreign song such as japanese,korean,hindustan and of cause english,from there we can see the gap of the quality of singing between us and theirs.
Not all of the singers in Malaysia can't sell their album, some of them did really good in their career like David had mention before,Dato' Siti Nurhaliza, Ning Baizura, or Pop Shuvit,their album sold really well.
The other reasons is maybe the song that has been compose, is not really suits the young generations nowadays, which has been expose to the better song,like i said foreign song.
