The program lets you include as many artists and albums as you like in the database; you can also add photos, profiles, extra info, playlists, etc... In addition, you can click play to listen to songs straight from the application itself.
Of course, any additional data about your music, including album covers, can be downloaded directly from the program. But beware, you can only download the information, not the songs.
Musicnizer is a very good music organizer to keep your entire collection perfectly organized at all times.
You can only add 20 albums to the test version
