Many people have said, and I happen to agree, that listening to Gaelic as much as possible is really important to learning it. So here are some suggestions on ways to listen. I've broken it down into three levels but, of course anyone of any level can listen to any of these and get benefit from them.
Beginners: if you are just starting out Speaking Our Language is a great tool. S.O.L is a Gaelic learning program. Some of them can be found on You Tube and all of them can be found on learngaelic.net. Another learning program is Can Seo which can be found on You Tube as well. Gaelic4parents.com also has a lot of simple phrases that you can listen to.
Intermediate learners: One great resourse is Island voices/Guthan nan Eilean who make great videos about life in the Western Isles. Their videos are on You tube but it is well worth it to check out their Clilstore units which have transcripts that you can click on if you don't know a word. Here is one of them
There are also some great videos on Learngaelic.net on lots of topics and you can choose to have Gaelic or English subtitles.
Also check out the Read aloud section of gaelic4parents.com. These are basically kids audio books.
Advanced learners: Listening to any program on Radio Nan Gaidheal is a good way to listen to Gaelic. News programs are good and it can be easier to pick up on what is being talked about if you know what is in the new. This can also help in picking up new words. The chat shows are great for hearing people speak at normal (fast) speed) as well as hearing speakers from all over.
Tobair an Dualchais and Am Baile also have great recordings
