vista..???? not sure though.. all DRM was the same. drm was
introduced long ago. since than, songs which are drm protected need
license to play it. if u try to play a DRM protected file and u
dont have the license, it will prompt u and ask for one. ifnot u
can't listen to that song.
DRM has cause many trouble. especially migrating Songs and license
to other computers. this is becase, microsoft only allow a maximum
of 5 times migrating of songs using the same license. if u exceeded
it, there goes your song, you wont be able to use it liao, and
thus, u waste money buying songs from websites.
