Hello, given there is no changer in the v, I purchased a 35 gig USB drive from Best Buy. There are 1034 songs uploaded to the drive. Yet, while using the random button, the highest number of a song that plays is 254. I know in the IT world, 255 is the upper limit, does that also affect the number of songs the system can play? Some songs are being repeated and some songs are never played. Thanks!
