Two things
1- $40 look like a rip of
2-The trial is as well a rip of.You can change 18 files ,but as soon as you start the program,IT SCANS ,not you by selecting some files you know have problem- and trial finish
If you hve a very good program you let people try it on let say 100 files
3-I you want to get free check on the top of the 18,you have to upload infs about songs.I am sure that people upload ifos like 'aaass htyug 1245-tango' to get free checks.
This is the kind of program who deserve a c ###k..but i did not find one
As i say this kind of program is something MJ must have .As a paying plugin ,not a free one.
With some others[find multiples copys,check quality for MP#,APE and OGG] this would put MJ on the top of any others
