Hi giantmike.....thanks for your response.
What I mean is that the music tracks won't play one after the other, after installing them in the MP3 player.
Hitting the play button results in the first track playing through and then the player goes into stop mode, so I have to hit play again, and so on.
I bought the player on eBay and the seller tells me that this is normal for MP3 players and that I need some software to "string the tracks together".
I guess if I was using a "Windows" computer, the software that came with the player would look after this.
