Most if not all music tracks will have a "tail" or "remainder" at the end consisting of reverb, delay effects, decay of an instrument, etc. or maybe the composer simply wants some sustain at the end of the track that overlaps the following loop a bit.
As such, the loop needs to start playing at a specified point shortly before its previous one has ended, resulting in a bit of an overlap. This can't be done with the Audio object's built-in looping.
However, this can be done with audio scheduling. Problem solved!
Or so I thought... It appears that Construct doesn't allow you to stack playback of identical music tracks, so when I go to play a new loop just before the end of the previous one (as to not cut off the remainder) it instead replaces the previous loop and...yep, cuts off the remainder.
This isn't a problem when using 2 different tracks (e.g. having a one-off intro track overlap the beginning of a different, looping track) so I don't understand why we can't also do that with multiple of the same track, unless it's some sort of safety measure to prevent people from doing this on accident (in which case there should just be a parameter to define how many "stacks" or "layers" of the same track can be played simultaneously - this would actually be very useful for sounds!)
Anyway, hopefully I've explained this well enough. 
Ashley would it be possible to allow this or add an option to do so? I can file a suggestion if needed. The only workarounds are to have a duplicate of the same music track with a different name and then alternate between the two, or play the music tracks from the sound folder...but obviously neither of those are a good idea lol.
