Backup from a previous iCloud backup
I've had iPhone 6 for long time
Had around 6000 songs on it, and it was my only copy because I had just sold my laptop
Connected to iTunes on desktop computer at work for synch / backup, and ended up losing all my music
Want to restore my music and go back to before I connected to iTunes on my desktop computer
Is a backup from iCloud from a previous version the best way to accomplish this?
Need someone to guide me through this and I cannot take my desktop computer to the Apple Store
