Sometimes I listen to long MP3s, 2 hours or more(Paul Oakenfold mixs and talk shows off the net). I was having problems with the songs stopping after a few minutes. I messed around for a while and found that if you use the wave edit program in Nero and resave the file under MP3pro, it plays all the way through. As and added bonus you can increase the Kb/s and the quality setting and the songs sound a lot better.
