Easiest way to compare duplicate tracks on different albums

[MikeMusic]

Check what tracks you already have - against the album you're thinking of buying

Usually time consuming
EG
Dusty Springfield's As and Bs to Best of Dusty, 20 odd tracks compared to 40 odd

Can be worse when you look at a compilation album compared the albums you have by that artist
Gets even worse of course when you bring in different versions, remixes stereo or mono mixes

In this day of free phone apps that do almost everything is there something ?

[MikeMusic]

Got it, or at least a way

Go to the relevant albums
Cut and paste track list into a database or spreadsheet.
Change the order to alpha and the dupes show up one of top of the other

Surely someone has already done freeware or an app for this.......
