zelenakadrian, Yes you can put an 8gb micro into this player but you need to be aware of Digital Restrictions Management DRM and SanDisk products.  Microsoft Windows will kill your app and SanDisk is on the list.  Just make sure your music is DRM free.

SanDisk is aware of a conflict with Microsoft but refuses to admit to the truth to customers.  SanDisk can blame Microsoft and SanDisk can sell new players.  SanDisk is suffering and becoming untrustworthy to the public.  Microsoft will kill this corporation.
