AIMP. Its great. Been using since forever.
Well if u have an android phone or tv, you could download cloudstream. It searches through many sources and has a nice ui. If it is any good for u then i recommend sorastream and superstream
Its really simple open cloudstream and go to their website page where u downloaded their app. From there click repositories, then click install to the repositories you want to download. It will redirect to the app and ask u if you want to download all providers. You could also do it manually and add the url to the app by copying the url. It is very simple and convinient.
Here is the link to the repos: https://cloudstream-on-fleek-co.ipns.dweb.link/repos/
Edit: typo
First for good info for rooting your phone check xda forums. They surely have a forum for ur phone and surely have someone who rooted it and has more experience and is willing to help out.
For a store u could use apkpure app store (no account needed) or apk mirror
Be careful when rooting because there are risks of bricking and such. Dont root ur main phone it might be risky since its ur first time.
I personally use AIMP. It has a built in converter it worked well for me
