Well for some time I think the one of my favourites is Stuart Hamm in Flow My Tears, great track, great bass line, triplets and tapping, everywhere in it, and melody of course
Sick Sad Little World from Incubus is also great bass liner one. So groovy, great too play it, if you play that riff faster and faster, he becomes a graet exercise
Angra's Ego Painted Grey has got great bass intro, tapping as well. Hard to repeat it
From Dream Theater - I just love bass line A Fortune In Lies, so crazy in the beginning of the song, I think that never will be able to play that
Bass in The Glass Prison, before JP solo and under solo, you know what I mean
And I love spooky As I Am bass flageolet intro...
