I use the free version. I have more than enough songs to play an hour and a half (at very least a couple of songs!) Every time it plays the SAME SONGS AND REPEATS THEM. I can skip a song a few times on the free version. Skips are used up trying to hear anything else. I might get one or two new songs by skipping. I have no choice where to start playing songs. I wish I could have found some way to contact them. User's recommendation: Check FREE VERSIONS of ALL - not “Trial Version”.
