People love consistency(have the same intro and outro), keep your like and subscribe comment for the reasons you mentioned, the music sounds like its being played in a coffee can, tho the volume was perfect. Have a sheet of paper with points to keep your thoughts somewhat on track, side tracks are great but only if you can bring your audience back to main point. Don't stress about entertaining people, millions of people literally seek out podcasts of peole just talking about random shit. Some use the pods for housework, driving, cleaning, to fall asleep etc.
