One can pop up Slacker on one's Android, hook it up to one's vehicle and drive around with awesome tunes. Or in a jam, if one forgets one's Ipod, one could pop up slacker and listen to great tunes at the gym. One can also look up some romantic tunes when one is having a private dinner night. One could even explore new music that one has never heard before. One can do many things, one can do it with others making it twos or threes.
IF YOU LOVE MUSIC, DO NOT SLACK ON YOUR MACK, and get SLACKER RADIO!!
