Mulitiple Files in Browser

[Nausea]

Hi there. Been using Live 6 demo for a while now and plan on purchasing an upgrade to the full version soon.... real soon! Right now I'm deciding on a midi controller and a soft synth so currently I use Ables just to mix mp3's. but one problem i've had is that i have multiple track file listings in my library browser due most likely to moving around tracks in finder's music folder somehow in an attempt to organize my music. Bad mistake. Now under some album folders in Ables browser, there are three copies of the same song and it drives me nutz!! Whats going on? How do i rectify this problem? Is there something i should do before i purchase my full V download?

And if anyone has any recommendations on a soft syth would be greatly appreciated.

cheers
