The program has a unique feature - automatic music recognition. This is a major advantage compared to MP3Tag. However, there is no batch processing. This is the main disadvantage. Therefore, it can be used to edit individual songs as an additional tool.
I have a large collection of recordings made with i-Sound Recorder and filling out tags manually was quite tiring. The developers advised to install this free add-on, which determines the Artist and Title automatically. I was skeptical, but the program was able to recognize almost all the recordings made in the last month.
