Waddup, kababayan! Anyway, this may be tricky depending on how you want BROADEN your Pinoy vocabulary since most are rock/love/pop songs. Usually it's more of practicing with Tagalog-speakers to get yourself familiarized with words and expressions. I have a Fil-Am friend here in Boston that had trouble putting words together and fluent speakers like my friends and I helped him by having convos in some TagLish (Tagalog and English) until he was comfortable enough to sew up sentences. Though he still had an American accent (understandable), we'd now have convos in Tagalog. It's totally cool if you feel uncomfortable or shy about mispronouncing some words/sentences, we all go through it at some point. At least you're putting in time and effort to LEARN about the Pinoy language
I'm sure you have friends/relatives that have access to TFC or anything related to Pinoy networks which can point out some of the pop culture trends that may help you.

(Pinoy hiphop is still a toss up for me because it's sounds weird and some are forced - imagine Migos or other mumble rappers but in Tagalog. But there are rappers like Gloc-9 that put out good songs so yeah)
These are some of the songs on top of my head that can help you. But if you're looking for nursery rhymes like "Bahay Kubo" or "Leron Leron Sinta" then that's a different ball game and I think you might want to ask your parents or other old folks about that
I hope this helps!
