Thanks to all posters on this issue! I've come to the same conclusions on my own same as your posts. The only reason I had considered what I did was that 75% of the library was listed last name first. But then with groups like " No Doubt", it seemed odd to list them as "Doubt. No".
Clint Black will be "Clint Black" not Black, Clint. I've figured out that it's actually easier to program MP3 tag to take the songs that are last name first followed by a coma and correct them to: first name followed by last name. I have around 14,000 songs to correct but it should go quickly.
Thanks again! dj.farrell
