If you are into recording and creating your own music, an audio editor program may be a good investment. An audio editor program allows you to save your own studio sessions or songs to modify later. Most include a metronome (to keep music and vocals in rhythm) and an audio mixer. The mixer allows you to adjust different music track settings like tone, pitch or volume. On some programs you can even 'beat match' between tracks, thus allowing for a smoother transition between songs. One audio editing program you may want to try is Blaze Media Pro, a program which is also a CD burner and converter. And, if you're recording a large file, most audio editors will be able to support your files with no problem at all. If you are using a multi-track editor, one thing to keep in mind is whether your sound card and memory capabilities are up to the task of handling large volumes of songs.
