Hello
Some funny answers are listed here .......
The people that have problems with this issue shouldn't have an I devices, let alone one. Steve jobs be rolling in his grave again.
There are two things going on here for the problem of the dreaded "Red square in red circle cannot play songs"
It's just telling you that you have that song, but it's not on your current device you are on, that's all full stop !
so it's not a bug not a error not an fault etc.
two things you can do is the following on your device that don't have the songs
To hide the songs that are not on your current device but are log with iTunes data base do the following
Settings | music | slide show all music to off
o that wasn't hard was it ......
Or you guessed it sync your entire music to your device ummm with all the songs I have not even my 128 iPad has enough space , that's why play lists comes into affect so well , make a play list up with the selected music you want to listen to and sync the play list of songs over to your desired device Simple 101 stuff.
