Then time to learn some slap-chop.

Probably the most fun you can have on a bass. Else yeah, pop, even rock can be quite boring.
I started with Blood Sugar Sax Magic and Rage Against The Machine, plus some rock stuff like Tool and Soundgarden. But I'd recommend actually starting with the fundamentals, instead of the other way round, like I did. Exercises, scales, techniques, metronome, the works. Not as fun, for sure. but starting too fast, and it's a sure way to get frustrated quick, and sloppy.
And if you're serious about this, don't get a Precision-style bass for slap either. Rather, get a Jazz Bass clone. They can get pretty good and pretty cheap. The cheap Ibanez SR range, I guess will be OK, but you'll really want a two pickup setups (bridge pickup bring up the shaprness) if you gonna practice some funk. Or even maybe something like a second hand Ibanez ATK, or a good Musicman clone.
As for amps, If you gonna practice pretty much on your own, an amp simulator / cheap pedal board with some decent cans (which you probably have already) would probably be better, rather than an actual crappy amp that's gonna sound terrible and wimpy, and no use, even in a band settings, plus it's gonna annoy the hell out of everyone around you.
And if you need wattage (at least 350W for band practice), go second hand. Much more bang for bucks, and plenty to choose from (and from decent brands too).
I used to watch DavidSinRock, early on. Really good kid. Kinda got weirder as time went by, but his earlier stuff is fun. Lots of Chili Peppers, Jackson Five, P-funk, funk-rock, and alternative rock. Good inspiration, and you can see the progression throughout the years.
Basically, learn, practice and play along anything you can get your hands on, from old funk masters (Bootsy Collins, Larry Gaham, James Jamerson, Louis Johnson), or new school (Flea, Zender, from early Jamiroquai).
