I completely agree and can't recommend this app enough. There's so many things going for it compared to everything else out there. I use it every day also after churning through all the other ones out there and never feeling satisfied. The total app size is like 25MB and doesn't even request the internet permission. With not having the internet permission you don't even have to worry about what data is being sent back to the developer - the answer is none. Despite being incredibly lightweight it's somehow got more features than many other apps, and implemented extremely well.

It's free but you do get a couple extra advanced features for a small IAP such as a ChromeCast plugin and auto playlists (Most Played etc). Despite not even needing any of the features I paid for the lifetime access simply because I find that much value in this app and when you come across a diamond like this app it makes you want to give back.
