i have a python script on a pi2 running the Mopidy 2 that receives serial commands over USB. The commands are linked to spotify playlists. So every time a command comes in, I execute:

`mpc clear`

and after a 0.1 second delay:

`mpc add spotify:user:blahblahblah`  
`mpc play`

this works most of the time, but every once in a while I get this (but it recovers after a few tries):

```

```

On the mopidy-spotify end it says that the playlist doesnt exist, but the link is correct and it gets it right after a few tries.

What I’ve noticed is that this failure happens randomly, but when it does, it takes a few tries to work (I have to send the serial commands 2-3 times) also other playlists work fine at the same time that one particular playlist gives the timeout error… i assume the other playlists are cached and that is why…

Could this be a connectivity issue? how can I debug this more?

Increase the debug logging level. You probably want `TRACE` level for libspotify loading time stuff to show up.

When using Musicbox I use an IR control to select and play a playlist. I always use mpc load then the name of the playlist so I end up with this

begin  
prog = irexec  
button = KEY\_3  
config = mpc stop; mpc clear; mpc load “Mumford and Sons”;mpc shuffle; mpc play;  
end

If it’s a single word title playlist you don’t need the " "  
You need to get the title exactly right including spaces.  
I don’t know if it will work if adding single tracks to a playlist using mpc add  
Using mpc stop as well as mpc clear seemed to work better for me.  
I haven’t got round to setting it up in Mopidy yet, but can’t think it will be much different.
