Trying to replicate your favourite tracks is a great way to learn synthesis skills. Amazing what you learn by intensive listening.
Put the original song in a Reason track, find a section featuring the synth you'd like to replicate, then listen to the same bar over and over, listening to how it sounds. Use headphones so your family/housemates don't kick you out
2nd the view that the waveform isn't all that helpful, because with many sounds, the uniqueness is from the modulation, and the wave changes over time. Also 2nd Selig's advice to try different synths and deconstruct patches. You should be able to tell straight away some commonly used techniques eg when sync has been used, ring modulation has been used, a fast pitch envelope has been used, when white noise is used to colour a sound etc. And also try to identify a synth's "signature sound". Vintage synths are especially easy to distinguish - eg Minimoog, Prophet 5, Jupiter 8, DX7. Complex modern softsynths are much harder to distinguish (to me anyway).
A couple of tips easily overlooked -
-- FX can be an impactful part of sound design, rather than just a mixing/ambience tool. Not just chorus, distortion etc but also delays and reverb.
-- Key voicings are also an impactful part of sound design. You may struggle to get those stabs to sound as grand as on your reference song, but while your single note sound thin, what happens if you also play a 5th above the root note, or an Octave below, or a triad?
-- Arrangement can impact sound design - eg rather than using a delay, how about playing the same note 1/16 after the original note, and then for the 2nd note, playing with lower velocity (and program velocity to impact filter cutoff). Techniques like that are often used too.
All this stuff can be overwhelming but just take one step at a time and realise that every one thing you learn, is one thing more you can use for your creative arsenal
