Considering what is stated in this description, this piece is largely successful.
It is not fair to say that 'everything' sounds like it was from radio. Rather, that quality is best given to the percussion because of their lacking bass. Usually, such sounds would cause a piece to lack depth, but the rest of the instruments fill in the empty areas, while providing an atmosphere. The 'radioed' percussion, consequently, does help in this case because much of tone and melody is in the synths. They mostly seem to provide the rhythm, upon which these two components build to make the composition.
How you structured it is admittedly repetitive, but that is not necessarily a degrading quality, especially in this. There are enough distinctions to sustain interest. The main loop --- the one that starts after the introductory phrase --- is spacy and relaxed, so there is not a lot of physical stress and much potential for adding anticipation and transitioning, which was done well throughout the song. The 'whistle' demonstrates that, with its appropriate introduction, variation, and voice. It really does sound like a moper "trying to whistle themselves a nicer tune" under a dull mindset greatly evidenced by this piece's instrumentation and note sequencing.
The one thing that could be considered a marring element is the fundamental use of a single-bar repetition. Adding a similar loop in addition to the main could reinforce the already strong tone. This was done somewhat in the beginning but then vanished. Maybe some some modest use of SFX could render the same effect.
In spite of that, this piece can make for BGM. I like it and nice work!
Thank you, I appreciate the advice. If I had the full version of FL Studio, I'd go back and put it to use. However, I will keep that all in mind for future pieces. Again, thanks. :)
