Hi Guys. Sorry to say some of your tracks are naff. Words are wrong. Words come up after they should have been sung. ( Most recent Hermans Hermits - I'm into Something Good) Spelling mistakes. Words round the wrong way...... Some songs don't flow which trips the singer up. Some have poor quality sound. Some are just out of key. Many songs on your packs are just not required. However we are having fun with what we have purchased and everyone is having a go. We tend to try and buy Multiplex singer assisted songs which is helpful to whoever is singing. We do have an option button to switch off Multiplex. www.solidgolddisco.co.uk
