अनुबाद - तुर्केली-अंग्रेजी - umarım favori müziklerimi beÄŸenirsin

I hope olmalıydı

in acording with source text, music must be put to plural.

"I hope you will like..."

perhaps use songs so it can be plural like source
but not really necessary: muzic is also good and can only be singular in english
hope without I is okay to keep a less formal tone like the source

If the original requires the use of a plural noun...What about

I hope you (will) like my favorite songs

?

i still believe it`s better without the "I", because it sounds less formal..
and though it doesnt really mean songs, but music in general, songs can be a better choice..

öznesi yok bu cümlenin.
