All audio CD authoring programs have a default 2 seconds pause between tracks. But most rap music are continuous and by breaking the long track into several tracks serves only the fast forward function on a CD player. But if you forget to check the “No Pause Between Tracks” checkbox on your music CD authoring software then the result will be abnormal between tracks. We advise our clients to either put everything in one track, or specifically tell us to have no pause between tracks.
If you compile your CD using NERO watch out the dialog as shown below.
