Have you ever been listening to a song, and thought "Hey, I would have played (written) a completely different bass line!" Maybe the bass line is just too weak and boring...or simply overwrought / over played / the groove doesn't fit the song. I'm NOT speaking to poor recording as much as I'm talking about bad composition relative to the song. And, if possible, can you think of songs that are popular or semi popular? What might YOU have done differently?
