CueMaster is a MP3 & Audio software developed by Bass-Z. After our trial and test, the software is proved to be official, secure and free. Here is the official description for CueMaster:

MarydownEditor: CueMaster is the best freeware cue sheet creator. Creating a cue sheet for a CD has never been so easy. CueMaster can retrieve CD track info from the free online album database FreeDB, or recover cuepoints from the MP3 file itself.

Cue sheets are hard to find these days. Many download sites and P2P programs offer full CD's in one big MP3 file, but finding the correct tracknames and lengths can take a lot of of time. Burning an audio CD results in 1 long 80 minute track instead of separate audio tracks. But not any more: we have the solution!
