Music cassettes have been around for years and will now show signs of wear. Some tapes have degraded and start to flake, making them unplayable. You may have a special compilation that you have put together or music that has sentimental values. Revive those old cassettes to CD or MP3, whether they are pre-recorded or a special compilation.
You have the right to back up any recordings you own and the cost to transfer is only 50p per track to CD. This includes song label and basic clean.
