Acoustica MP3 CD Burner does not search the Internet for music, it only searches your computer's hard drive(s).
If you know the songs are already on your computer, but they are still not coming up, try this: In MP3 CD Burner, click on the File menu and select Preferences. In the Sound Scan preferences, make sure that your song folder is listed as one of the scanned folders, and then search again.
If that doesn't help, try dragging the song from Windows and dropping it in MP3 CD Burner's song list. If the song refuses to load, it may be copy-protected and you won't be able to use it with our software.
You can use MP3 CD Burner to "rip" or copy songs from CDs you already own.
