Best budget data recovery software - Windows 10

Hi there,

I stupidly saved 4 Studio one ver. 4 song files along with all their data on an external HD which is now not functioning correctly (as there is a problem reading partitions).

I'm running windows 10. 

How can I best recover the data and get these songs up and running quickly again please?

I have tried a number of data recovery programs which can find the files however so far, EaseUs seems to be the only program to find the correct file structure however to recover these files will cost me $69 for one month!

Can anyone recommend a reliable and cheaper alternative software package please.

Or suggest how I might resurrect these songs again from all the separate files found - if I use an alternative data recovery software package.

Many thanks in advance :)
