I just heard someone say SB19 is all they know about OPM (Original Pilipino Music), and I died a little inside. (I've got nothing against SB19, but to condense all of OPM to just them is a tragedy). And as someone who credits Tagalog OPM as one of the reasons I'm still fluent in the language, I decided to make a list to help out those who want to dip their toes in Filipino music.
(Note: this is a very, very short list of even the ones I know of, since Tumblr apparently has a 100-link limit to their posts. I kept to those who have released something in the last several years, while trying to find a balanced mix of mainstream artists and lesser known ones.)

Like I said, this is a really short list. It doesn't include 90s and '00s megastars that really made their mark in the industry like Regine Velasquez, MYMP, Gary V., Aegis, etc.
Please don't expect Filipino music to be like western pop or east Asian pop, that happens to be in a different language. While some artists and their songs do have that "international" flavour, Philippine music in general has a different vibe. Yes, even when the song is in English. Don't expect multi-million dollar production budgets. OPM is characterized first and foremost by hugot (that feeling of tugging on your heartstrings), not flashiness. Also important are vocal ability and creative wordplay. Most of our singers write their own songs.
I also suggest digging past the mainstream pop idols, who tend to recycle old hits and cover other songs. There are a lot of indie gems in OPM, the ones who are really producing music with spirit and strength and good messages. Social media has allowed these artists to reach a mass audience, so they're not difficult to find. We're in a great era in OPM, where more and more songs in other regional languages are being written and produced. There are pop songs now in Kapampangan, Bikol, Tausug, etc.
Also, while many of the musicians on this list are people I genuinely enjoy listening to and support, there are some I've included to show the wide breadth of music in the country, but whom I do not particularly endorse. Like many people in the entertainment industry, some individuals/bands featured here are embroiled in controversy, and I don't necessarily condone their actions.
