best pinkie excercise songs for bass guitar (pinkie stretch across frets)

[blackmetalpunk84]

what bass guitar songs use the most pinkie reaches ???  for example fret 1 to fret 4, or fret 5, 6, on g string. 

or fret 5 on g string to fret 9 D string.  im looking for some stretchy songs like that, since my pinkie fringer, for over 20 years on/off playing, is still rather useless, and im looking to find some real hand stretching songs.  thanks.

It's a really good song to exercise your Pinkie.

My pinkie finger started to work better after really trying to learn some Rush songs. They're not the biggest stretches in the world but playing The Trees a trillion times really seemed to help with my finger dexterity and pinkie strength.
