I plugged my phone into my car stereo and played music.

What are some good phone apps to stream music that don't eat a ton of data?
My phone runs android.
I do not own any apple products.

How do you kids buy music nowadays?
Suggestions please.

I listen to Pandora, and buy CDs.

I'm old.

I don't have a smartphone. I have gotten iPods as gifts from several men. I use an iPod classic, it has the wheel that they no longer make. I think it holds something like 18,000 songs. I only have hundreds on it. I always check the free ones on iTunes every week.

I'm a music publisher.

As a consumer, I kinda like Pandora -- I set up a "radio station" based on my favorite performers or my favorite songs, and Pandora plays similar non-stop.  That's pretty nice.  For a cheap subscription, you get all that commercial free.

But as a music publisher, I hate Pandora, because Pandora works hard to avoid paying songwriters & publishers & all the other people who created the music and made it available for you to enjoy.

So, my official stance -- avoid Pandora, and try Spotify instead:
...  It has a much bigger catalog of songs than Pandora,
...  You can set up Pandora-like radio stations, but
...  You can also create playlists, and
...  You can also find & play specific songs that you want to hear,
...  Spotify does compensate the creators of the music you are enjoying.

Spotify isn't the only streaming music service -- there are tons of others, and nearly all compensate the music creators.  Search for those.  But Spotify gets my consumer & publisher endorsement -- I haven't tried all the others.  (Rumor has it that Apple is announcing a music streaming service in about 2 hours).

So, that's my take.

I went from, mix tapes, ( dual tape deck ) to masses of CDs with a zillion watt component system, to the wheel having iPod, to iTunes on the laptop, to XMRadio, to Pandora.

But it's all Spotify now baby...

I use Soundhound to identify new music on the car radio and in stores/restaurants, or that the model is playing and can add the song to my Spotify playlists in seconds!!!
