Not entirely true.
Not even a tenth of the songs here are mario remixes... maybe remixes. Most people do it for popularity.
The kick all the time is really a bit annoying. The pad in the start is ok, but sounds like a messed up melody of the original.
The lead thing is seriously off-key.
The next thing is kinda cool though! Like the lead you had in there. The drum work is good here, but it's a bit glitchy and repetitive. did you record your own voice in this or something? Sounds a bit like so. In the end you keep doing the same things and end it off like usual.
What's that noise all the time? sounds liike it's done on an old film record.
Ok good work on this! I enjoyed it.
