Thank you so much for the advice regarding CopyTrans, it was perfect for my needs.

I had to run a factory reset on my pc, not even considering the music I had stored on here, and I lost everything.
CopyTrans allows you to copy 100 tracks in trial mode, then if you have more, you can purchase the software.
It's not expensive, around £15 (or whatever the equivalent $20usd is at the moment) but it enabled me to gain the confidence in the product in the trial mode then I did go on and buy it to download the remainder of my music.
Brilliant, really helpful, thank you guys.
