My time to shine:
1. First of all, since you've said you don't want to download any music, I don't see why you need a 1TB SD card? Even if you were downloading music, to use up all of that 1TB, you'd need to download over 100,000 songs since most songs are under 5MB (10,000MB = 1TB)
2. Slowjoe mentioned trying YouTube premium but I myself refuse to pay for any kind of software. Fortunately, since you're an Android User, you can get Youtube Vanced. Here's the link:
External Link/Members OnlyYoutube Vanced is Youtube (And Youtube Music) but all the premium features have been unlocked and are free. That means no ads, unlimited music, and playing music while your phone is locked.
Every song that is available on YouTube will now be available on your phone. For free.
3. I know your car doesn't have bluetooth and my first car had the same issue and I got tired of burning CDs. What you can do is get a
FM Bluetooth transmitter. Just search for the bold three words on Amazon and it should be there. I've attached an image of what it looks like.
Hidden Image/Members OnlyYou plug it into your car where your charger normally goes.
You then select a radio frequency on the transmitter by twisting the dial. The default of 108.00 should be okay though.
You then select the same frequency on your car's actual radio.
You connect to the transmitter using bluetooth on your phone (You don't need a cable but you can charge your phone as well if you want). Now, whenever you play music on your phone, it will play through the radio. Plus, you don't have to go through the above process again. Your phone will automatically connect to the transmitter as soon as you turn it on.
Final: If you have any issues let me know. I use Vanced myself and had an FM transmitter as well so can help you out with any problems.
