Iron Maiden - steve harris bass lines are great ; early stuff from killers, somewhere in time, number of the beast, piece of mind, 7th son of a 7th son. etc etc
Steely Dan - just pick any of their albums; they had some really good session musicians.
Herbie Hancock - Headhunters.
Joni mitchell - hegira (the late great jaco pastorius plays on a couple of tunes)
Also, check out Scott Devine's youtube channel (scott's bass lessons) - his project live band has three solid tunes that are very bass orientated.
Thin lizzy - waiting for an alibi. Of all the tunes I used to play bass on back when I was in a band, I enjoyed the energy and the groove of this one the most.
EDIT: add also 'rosalie' and 'the cowboy song'. ah, happy days.
Megadeth - anything off rust in peace - if you can hear it in the mix as that album is just so tight.
Santana - those latin beats get me every time. It's not about the notes, it's all about the groove.... oye como va, fried neckbones (a lot of santana's early music is very raw - think woodstock era).
there's probably more that escape me right now.
