Hello my friend. I understand what you mean. Listening to another language is far more difficult than reading it because when you read you see every letter and every syllable of every word. When we English speakers speak, and especially when we sing, we do not take care to carefully enunciate each word and pronounce each syllable most of the time, so the phenomenon you are experiencing is real. Even as I say that, I would suggest that you listen more closely because although we attempt to pronounce the full word, we sometimes "swallow" portions, so I call the portions that you don't hear or don't heal well enough, swallowed syllables. Most of us say ev'ry (every), cam'ra(camera), lab'ratory (laboratory). We turn a lot of t's that appear in the middle of words into d's, for instance, ledder (letter) and we make the contraction wanna from want to (the two t's are totally swallowed in this instance). In time, as you listen more intently, you will hear a lot of the endings. The are swallowed because of laziness or just the lack of emphasizing all syllables equally. Incidentaly, the t in listen is silent. (if I say silent in a lazy way, you will not hear the t at the end and if I say end in a soft way you will not hear the d at the end. I hope this helps.
