Methods of rendering of unpaid media assets from an on-line merchandiser to a user are disclosed by the use of handheld media players. One embodiment uses the idle screen to display metadata of an unpaid asset when another paid asset is being played. Another embodiment employs the switching-on screen of the player. Recommended unpaid assets by the merchandiser are delivered and stored in the unused storage capacity of the player. The unpaid assets are invisible to the user except that when they are selected by the processor and are displayed on the mentioned screens. The unpaid assets are organized in a single structure as those media assets owned by the user. The capacity occupied by the unpaid media assets is adjusted dynamically based upon the required capacity by the user at a specific time. The media assets stored are managed based on their assigned priorities. The user can pay the on-line merchandiser after the recommended asset is selected through a method that the assigned credits to the user are deducted and the user pays for the on-line merchandiser when next time he or she is connected to the merchandiser through a general purpose computing device.
