Hey Pedro:
Thought somebody should listen to your tune & comment on it.
Keeping in mind that it is a rough mix, there is alot I would suggest.
The first thing that caught my ear was the drum machine. I would definitely change the "snare" beat on the song. It sounds more like a glitch or a skipping sound than a snare.
The backing vocals came in late, were a little off key at parts, and unevenly mixed.
The lyrics were too bland, but that may be your translation of them to English.
On the plus side, I think your Swedish accent works on this type of tune. It adds style to it.
And I liked the piano on it, it was a nice touch throughout the song.
The melody & song structure was good on it too.
In short, to fix the rough mix:
Kill the drum machine, or at least change the snare sound.
Have the backing vocals tighten up.
Trying to sing it in English is obviously the way to make money with it, but record it first in your native Swedish dialect, then see how others may translate it.
Happy Recording!
