This is really strange. I have burned BurnAware Free) 20 or 30 CDs (Sony CD-R, 700 MB discs) of 50s & 6os Rock and Roll in mp3 format for listening in my car (2011 Toyota Highlander). All have worked fine except one! I have a single CD that gets to a particular point and starts over. The original disc had 697 MB and 342 files (songs). This is about normal for what I have burned. The "restart" occurs around the 254th file. I have re-burned the disc. I have removed files in the +/- area of 254 with the same outcome. I have replaced the files in the +/- area of 254 with different files with the same outcome. The original disc and the modified discs all play fine from my desk top hard drive, and from my desk top CD drive.
