That's the only site I know is legit as well, roses4me.
On the Tyler site, it talks about a Tennessee business man named Gerald Dodd who started this site. If you google his name, you only get radiologist and a minister. Plus, there isn't any info on the Tyler Music Group itself. They also place this disclaimer on their "interview" with Taylor's ex-producer:
Producer, William Smith requested we not use these articles. The articles regarding William Smith and Taylor Hicks are a matter of public record and we are allowed to use them. At Mr. Smith’s request, he wanted us to inform you he has no current affiliation with The Tyler Music Group, Taylor Hicks, American Idol and all its affiliate companies.
