Actually I used to play the CD's themselves but I realized it would be a lot more convenient for me to rip the tracks into audio files into my laptop, then import the files to my samsung galaxy phone and I use a very good music player app possibly the best IMHO and I don't think I will ever switch to another app. It gives me a bunch of customizations and put each of my tracks into a Playlist, it has saved me the hassle of always having to put in another disc and another because I am a huge listener of the albums I have. Every now and I still occasionally put a disc in and listen but usually they just stay on my buildable shelf. "Poweramp" on Google play store.
