Use the tracks. PG has given you that right as long as you are not doing covers. For covers, you must adhere to the copyright laws. For original songs, you own the rights to the tracks you create.

As has been said by others having music published, I also have tracks that were and are being used commercially on TV and in films. There have been no problems regrading the use of any of my tracks. Knowing that PG has given me the right to use them, I simply claim them as my own and that I own 100% of the controlling interest and rights. That's all the publishers and libraries want to know. It's in the contract in writing and that's all that matters.

Add nothing that adds nothing to the music.
You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
