Many songs on the radio over the decades have a very similar or even identical song structure (verse chorus verse, et al), certain frequency ranges (bass, mids, highs) are prominent in certain areas of the song and less prominent in others, the transition spaces can also be very similar in many songs. So yeah we don't need to reinvent the wheel.

Now, is there any DAW or third party software that has ready made templates for arrangment, so you can fill up yourself?

Thanks in advance

 

There are lots and lots of templates for Ableton Live out there, in .als or .alp format. Most of them are dance music oriented. Many you can download from the sister site. Others are free. It's fun to play with them, edit them, add vsts, jam etc. I do it all the time.
As far as I know, there are templates for FL Studio and Cubase also, but I don't use these DAWs. I believe there is nothing for Reaper, Samplitude or Waveform.

 

Import any songs midi files, apply your own synths/instruments to each track, edit/modify to your liking

 

You don't mention which DAW you are using, but I have tried them all and to roll your own templates is easy in any of them. Pick your generic song that for some reason you want to copy. Put the wav file in your daw. plug in its bpm and time signature . Put markers at the relevant junctures...verse 1 verse2 etc. Colour markers to taste. Remove song file. Save as template and name it 'generic shit' You can then use Ozone's match EQ funtion with your generic track as a reference to make sure it will sound the same. After this you might need to use your ears a bit
