Here are his comments about another online jihadi, Asadullah al-Shishani, whose name you might recognize from my interactions with him in recent months. Al-Shishani seems to have been a major inspiration on al-Shishani as you can tell:
Jazaakum Allahu khairan akhii, may Allah reward you for the uploads. Also, may Allah reward Asadullah al-Shishaanii for the nashiid. Maa sha’a Allah the kuffar are starting to follow him quite a bit. I have run across articles on his nashiids two or three times now alxamdulillah.
The article above mentions his nashiid maa sha’a Allah.
