In this case, ALMOND BUTTER is likely an arbitrary trademark because it has nothing to do with the underlying music services. Arbitrary trademarks "comprise words that are in common linguistic use but, when used to identify particular goods or services, do not suggest or describe a significant ingredient, quality, or characteristic of the goods or services." TMEP 1209.01(a). APPLE for computers is a good example of an arbitrary trademark. Arbitrary marks are much stronger than descriptive trademarks and therefore typically enjoy a greater degree of protection. Such marks can also be registered on the Principal Register without a showing of acquired distinctiveness.
This ALMOND BUTTER application is a good example of two important trademark concepts - (1) merely descriptive trademarks are weak, more difficult to register, and should be avoided, if possible and (2) the underlying goods and services play an important role in determining a trademark's strength (use of a word on some goods may be generic while use of the same word on other goods may be arbitrary).
In sum, had this application covered "almond butter" rather than music services, the applicant would have been in trouble. However, because the underlying services [probably] have nothing to do with almond butter, the risk of a refusal for being generic or descriptive is probably not likely (although there are several other issues that could prevent registration, such as creating a likelihood of confusion with a mark in a previously filed application or registration).
