I seem to spend so much time finding enough tracks to fit on a 128meg player and then I find sometimes theres a couple tracks I wish I hadn't bothered with in the first place. Also I find my most common activity is to put repeat on for one track only and listen to that continously for a while. I know you can program tracks but I tend to just hit play and play the lot and just hit repeat for individual tracks. Do I need more memory? I might add that I've used my player quite a few times with only about 25-30 meg used as I've only loaded on about 6 tracks. Just curious how people get on with the 512meg models and how they fill them up and organise tracks etc? Also its worth pointing out that as I use mine for cycling so once I set the player going I don't really have access to the buttons and it will play for about 35 minutes non stop (my commute time). Obviously if your walking or using one on a train/car its different you have a hands on option to change tracks etc.
