*2025-10-06, version 4.2.5*

iSoongはプレイリストを作れるだけでなく、エフェクト機能でピッチを変更したり速さを変えたりということが簡単にできるようになります。
色々使ってて便利な機能は多いですが、エフェクトを大きなホールに設定するとコンサートのような音響で音楽が聴けるところが特に気に入っています。

### 3/5 — これは使えると思ったら

*2025-09-28, version 4.2.5*

CDを買ってリッピングして聞いたかったのですがドラマCDなのでファイルを個別リスト化して使いたくレビューを見てこちらのアプリを試してみたのですが曲が思い通りにリスト化されてくれてこれは行ける！と思ってまたいくつか追加したら固まってアプリを閉じで再度入っても固まったままで削除しました
悲しい

### 5/5 — リストを作るのが楽しくなる

*2025-09-14, version 4.2.5*

### 5/5 — 使いやすさ〇

*2025-09-04, version 4.2.5*

操作性もいいし視覚的にもリストを管理しやすくて使いやすい。おかげでお気に入りの曲が増えていってもリストが散らかることなく管理できてる。以前はiPhoneの音量を一番低くしても音が大きすぎたが、この前のアップデートでアプリ側で音量の調整ができるようになってより使いやすくなった。細かい部分だけどこういう調整はありがたい。

### 3/5 — ポイント機能

*2025-08-29, version 4.2.4*

曲によって再生する範囲を登録できるからお気に入りの曲のサビだけを聞いたり、特定の部分だけをリピートしてカラオケ練習に使えたりするのが便利でした。プレイリストも見やすいしお気に入りのプレイヤーアプリです。

### 2/5 — どうやってするのか、分かりません。曲は何を押したらいいんですか？全然分かりません。😭😢

曲が聞けません。何をして、曲を聴くんですか？ほんと分かりません。😭

### 5/5 — 機能が豊富

*2025-08-18, version 4.2.4*

ただの音楽プレイヤーとしても充分なんだけど、それに加えてエフェクトを加えて再生できたり、機能が豊富でした。ポイント機能における開始ポイントと終了ポイントを指定できる機能まで付いているので、曲の特定のフレーズを聴きたい時にとても便利です。
