Lead Overs
Obviously when reconstructing songs, it is vital to properly connect parts to make a seamless listening possible.
A good way to avoid repetition during such is a lead over
1) Lead1
2) Lead2
3) Lead3
(Yes I <3 Nier)
are good examples and the songs emselves can easily be listened ad nauseum as they never get boring.
Therefore it makes sense to try and interrupt a song part with such musical devices.
