Sometimes it will lock up on me and I have to skip to the next track. Other times it will forget my password, forcing me to close the app and reopen it. I've never had to pull the battery. If I use a task killer on it and restart it's usually okay. From my own experience, it seems the app can't handle the data dropping from 3G to 1X. Whenever I have a problem, I notice my phone displays 1X. That's just a guess though.

 

I've had to skip tracks a couple of times, seems to be on 1x at that time. I also had to FC once. Finally, it doesnt allow me to cache stations. Is caching only allowed on the full version? The error I get says I have too many stations cached, but the truth is there are none cached, since it wont let me.

 

You need Slacker Plus. I used the trial and had problems with that also. The app would only let me access my cached stations. I couldn't get to my favorites that weren't cached.

 

Was having issues with Slacker skipping when connected via the headset to the car MP3 jack. Seems the 3.5mm plug conflicts with the jack thinking your asking to skip (same switch that activates end call on head phones). Try it with no headset connected and see if it functions properly, if so you've also found the source. I'm not sure where to purchase a 3.5mm cable that won't interfere.

 

Many have reported this problem with cheap 3.5mm cables like ones from Radio shack (myself included). Went to a store that had a large selection of electronics stuff and found a retractable cord with 3.5mm ends that were gold instead of chrome and have had zero issues since. Cable cost me $10.

 

My trouble with slacker is they play commercials. Which is why I stick with pandora.

 

Should be noted that the "commercials" are very limited. I've had constant problems with Slacker, particularly when streaming in areas of low signal (won't play next song, or I get an error requiring me to restart/hit play). If you decided to cache songs however it works great, and is one of the only reasons I use it over other streaming apps.

Basically: Yes, I do experience issues requiring me to skip a song or hit play again. Yes, it's annoying. My solution? Cache station. I've got a dedicated MP3 player but it's in need of some repairs, so until then I'm using Slacker as my primary music player on the Incredible.
