If you played in a real band, you would never use the same intro twice. You would never play two songs with the exact same groove. If you only use 25 styles or so, you are using them at LEAST twice or three times (or more) each night.

Whether you are going for 'just like the record' or whether you are going for your OWN version of a tune, you are short-changing your audience to recycle the same style over and over just because it's convenient (or you can't find another style that works).

But that's just me...
