really gave me nostalgia for old wcw wrestling theme songs really like it

You could probably cut out that hum by eqing out the particular frequency or applying multiband compression

End result is muddy, bar rock-ish. I do like your lead playing. You've got potential if you start seriously songwriting, find yourself a DAW that can support vsts, a bass and drum set in particular. I have recommendations if you're interested :)

Overall, sounds nice, even given the limitations of software and hardware.
