You can train yourself to recognize intervals and notes in songs. The quickest way is with the see, say, do method. Your brain will visualize the interval at the same time that your fingers play it, your voice sings it (or speaks it, if you are shy), and your ear hears it (you must listen critically to what you are doing).

Sing the numbers in tune with the pitch you are playing. Sing an octave lower or higher if you cant reach the pitch. You will still learn the intervals no matter the octave.

The pattern shown starts in A. Use the G form scale, starting with the fourth finger on the fifth fret. Play the numbers shown in the scale form in the order shown on the ear training chart. Move the whole scale form up one fret and repeat it. Keep going up the neck as far as you want.

If you do this everyday after your warm-ups, you will soon be able to recognize intervals in songs and licks that you hear. It will be much easier to figure out lead solos and chord progressions then.
