My guitar always gets out of tune, because of someone playing with the tuners or an accidental hit on the tuning pegs . It would be great to have a tuning pegs locking system.

Music players always like to share what they know and have! And in sharing tabs there is not always a PC near. It would be cool to have a software that can be used on cellphones exactly as the software called "guitarpro" which can also handle the same file type ".gp4".

I read about people complaining about neighbours that take music to a high level, or car that passes at night and disturbs the neighborhood with its boom boom woofers. There is a way to handle this problem and it's in using the new technologies provided.

Everyone has old tapes. It would be cool to be able to listen to them on the PC. A tape-rom, just like the CD-rom could be made and althought it could be used to easely copy music from the tape to the PC and then to a CD.

When anyone listens to music, he takes the volume to a high level, because he enjoys it like that. One of the differences that the volume makes is the vibrations that causes the speakers in the human body. To enjoy more these vibrations a simple system of vibrators planted in a comfortable chair, attached to the hi-fi system could vibrate according to the song you hear.
