I am working with my mp3 files and have cleaned up a LOT with artist names, album art, etc and have been transferring songs onto my mp3 player, but I have been having this issue with many artists.
For example, I have 43 songs by The 5th Dimension, and when I transfer the files onto my mp3 player (Sandisk), when I select "Artists" The 5th Dimension has 2 entries- 1 has 42 songs and the other has "Up, Up and Away". This problem occurs on more than one artist.
I've emailed Sandisk, and their reply was to right click the file, check properties, then make certain that the Artist and Contributing Artist fields are typed in exactly the same. I've done this, but the problem still persists.
I created this screenshot and rearranged the columns to show the tag column source. Thanks in advance for any ideas on how I can fix this!!
