The Solution is easy.
You detected that you practise these songs which takes a lot of time instead using a program which can do it automatically.
Sorry but that's your fault.
Is it easier that way? Yes
Do you safe a lot of time? Yes
Does anyone except you care who just wanna enjoy music? No
It seems like you are just angry that you:
a) wasted a lot of time practising these songs or
b) don't know how to use these programs.
In other words: Deal with real problems, this isn't one.
