It depends on your music collection, I’ve tried the trial and for my collection it was a waste. Have a look at Beatunes, it’s GUI looks like ITunes you can try before you buy to. Not will it help sort your tags it find the key and highlights duplicates. You can make playlist and it have a function like genie which will create auto playlist based on criteria specified by you. So for example you could want 100 Tech house tracks between 125 and 128bpm in key A to D. If you have a large s collection the initial analysis can take a long time but it’s worth. You’ll need an Internet connection for it to check online databases it will show what it thinks the results should and won’t make changes without authorisation.
I have a collection of over 100,000 tracks which took about 2 months to run through. It didn’t 100% but I don’t think and programme can be but for what it cost it’s worth it IMO.
