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 £4.50p per side (any size) to CD. This includes song label and basic clean.
