MP3 player with albums that open and close

[RJSJR]

With my MP3 player I download to albums. When I open an album to play the songs, upon finishing the album I would like to upload the songs back into the album and download the next album. However, I can't upload the songs, so when I download the next album my MP3 player has the songs from both albums open and I have to jump or passover the songs of that first downloaded album that I no longer have an interest in hearing at this time. Does anyone know of an MP3 player that will allow me to upload back into the album on the MP3 palyer the songs of that album?
