I'm really going through these streaming outfits about as fast as my Chevy goes through gasoline. I never found everything that met my wishlist with the streaming companies thus far. Oh to be sure each one did some things right, but all of them I found lacking in much of what I was looking for. So after recently canceling the last one (Spotify) I was considering going back to Tidal for another go around, but while on my Hawaii trip this year my smartphones music player app choked somehow and wouldn't play anything in the phones memory and while on the plane I opened up google play music app just to try to get something playing on the headphones and since have found much of what I was missing from the other streams. First thing after signing up for the service it actually wanted to know what I like, my tastes, genre, artists etc. This could be as extensive or as simple as I wanted. I spent a good 15 minutes checking boxes of music I like now. Then I started playing my music I loaded before leaving home but this time I had the option to thumbs up or down my own music! This is huge to me since it bases recommendations to an extent on likes and it seems this will save a lot of time in finding relevant recommendations for me which is probably the main reason I am interested in streaming at all anyway. As for sound quality, was tough to tell the difference between 320 Mp3 I loaded and Google streamed music however that is still to be determined. It doesn't sound half bad at all really and I tend to be a bit fussy about sq in any source. Bottom line i am cautiously optimistic about Google. It seems like they did at least the initial setup as well as I could ask for. It has already put out some promising and interesting playlists based on likes as well as the initial questionnaire (which can also be added to). Whether google will screw this up like they often do is anyone's guess but I think it has potential for if not greatness, at least a decent service for those like me who are just after new material which to play or purchase.
