some artists are not playing on my devices

[bsayan]

hello,

i have been listening wiz khalifa for a long time, but for a few days i cant listen him. when i click to any song he has, i get an error says that '' this song is not available''. i asked my homemate to try to listen wiz khalifa and he did not have any problem listening. we are using the same wireless network in the home, so this issue is not a network based issue. i hope you can help me with this problem.
