Personally I like the search and playlist of slacker over pandora.. but slacker radios quality (on my cell phone) is far superior to that of pandora..
I may be mistaken because i pay for the slacker service(4 bucks monthly)
so the high quality may be a perk of the membership.. but i do know no ads.. and unlimited skips are membership only'
Recently they just updated the version and i no longer have problems with the program freezing or loading.. also noticed another playlist that you can cache onto your device called favorites. and this is just a list of the songs you have "hearted" while listening to any station.. and then it will suggest similar songs to those you have "liked".. its the best feature ive found in any online music program.. because like most people, i listen to all sorts of genres and artist.. and now i dont have to decide ahead of time what im in the mood to listen too,..
pandora didnt ever play what i wanted it to... and seemed to favor certain artist..
oh also theres a news update option and a stand-up comedy station (for paid users only.. i believe)
honestly sound quality was determining factor for me since i have a nice car stereo system distortion was noticeable and embarrassing at times with pandora.. soo much more i could add but hope this helps a little
just my .02 cents
it has been a while since ive even used pandora so they may have recitfied the issues..the only wayto find out is try em..
i believe there is a 24 hr refund policy on all apps on android... at least there used to be..
