Findenzio,
How are you man? I'm a fan of your music and think you have awesome production skillz when it comes to this genre, so the first thing I would say it do not stop! Your one of the best for this radio pop production on this forum IMO.
This track is a very good tune but needs some refinement.
(1) The chorus needs to stand out a little more, on the first listen I didn't get it. I would put in a sustained pad in the high octave range (not on the first chorus though) and I would double a vocal up singing in a higher range. I would also play a synth in the background doubling the melody line "first class" (could be a good title name).
(2)The intro guitar is really cool and really would like to hear more of it. The synth that follows, although works could do with being sent more the background and letting that guitar plucking do more work. I would also introduce it later in the song (a good point is where the kick drum comes in on a verse near the middle, plenty of sonic space there). Also I would tweak that synth if you can, sounds a bit "cheapy", something with more sine wave movement maybe.
(3) I think your vocals on the rap need to be distinguished from your singing vocals somehow to help differentiate. How about a more delayed effect on your singing vocals while shorter reverb on the raps, and doubled up.
(4) Your vocals could so with a little brush up too, I know you have been on here before and I understand we all have what we have. Theyre fine, but could do with some melodyne on the singing parts and play with the beat a bit more on the rap, spit those words in between the snare beats (easier said that done I know!).
(5) I think the arrangement doesn't help this track. All the parts are good but not structured for ease of the listener. That "ooh,ooh,ooh" part is great in the first verse, but should really come back in again in the song besides the end. The second part of the first verse has a rap, then the second verse starts with a rap. Then verse 1 comes back in at the end?! I'd bring the chorus back in at 0:58, that rap (although really cool) is dropping the momentum, keep it for later. It needs a bridge which really changes the song up (and help lengthen it up to 3 minutes). How about after the third chorus, stripping the song down, to those "ooh,ooh,oohs" and the guitar intro type thing, building it up with a filtered arp and snare movement while singing ("fight if off" etc and chanting every second line "wonderful to live/First class") before belting back in with the final chorus. For example, the part you have at the end with the snare clap, is perfect to start a bridge with. End the song after the chorus with the ooh,ooh,ooh and intro guitar again. I'm I making it any clear?
(6) BTW I like the spanish language in this, really give it some character. Maybe a section to many in spanish, but definietly do not write it all in english.
Good stuff mate, I wrote a long response cos I like it (these may sound negative but they are only suggested improvements on a damn solid catchy track). If you need any other set of ears I'm happy to help or if you would like me to sing on a section to beef it up, send me the lyrics and I can notch out a take for you to use at your disposal.
*Robby, I don't know what's going on with that last response. Cut it out mate. Go make some music!
